Description:
A prominent problem in Computer Vision is multi-image matching, where the task is to find matches (i.e, coordinates of image points that derive from the same 3D point) across multiple images. This can be formalized as an optimization problem (called “synchronization”) over permutation matrices, and solved via eigenvalue decomposition. The goal of this thesis is to develop a new method for multi-image matching based on permutation matrices.

Description:
3D reconstruction is an important problem in Computer Vision grounded in projective geometry. It is known that 3D reconstruction from two images can not be performed in some degenerate cases, for example when the 3D scene is a critical surface (a hyperboloid, a cone, two planes) and the cameras lie on that surface. The goal of this thesis is to develop a new method for detecting degenerate configurations in practice. A good mathematical background is preferred but not mandatory.

Description
Description:
As 6G networks evolve to use higher frequencies and larger MIMO arrays, communication will increasingly occur in the near-field, unlike today’s far-field systems. This shift has significant implications for how channels are modeled, estimated, and how communication systems are designed. Near-field communication introduces unique challenges, such as the need for new channel models that account for spatial variations over short distances and more complex, yet critical, channel estimation techniques. Precoding and equalization strategies must also be reimagined to address the non-uniform distribution of signals and the potential for increased interference in dense network environments.
This thesis will explore these challenges by developing advanced signal processing techniques tailored for near-field conditions in 6G networks. It will focus on improving channel modeling, estimation, precoding, and equalization for high-frequency, dense scenarios. Additionally, the research will investigate the use of machine learning to enhance these techniques, offering more adaptive and robust solutions. The goal is to make a significant contribution to 6G technology by addressing the critical challenges of near-field communication with both traditional and machine learning-based approaches.

https://cassano.faculty.polimi.it/Description
Description:
The activities will be conducted in the framework of the FOPAC project, led by TSD-Space and founded by the Italian Space Agency. The FOPAC’s goal is to develop an active motion control system for the focal plane of electro-optical payloads adopted in Earth observation applications to enhance image quality in terms of spatial resolution and Signal-to-Noise Ratio (SNR). These platforms often feature telescopes with limited focal length and aperture, and less accurate attitude control systems. FOPAC can be utilized for implementing active focal plane stabilization techniques and pixel-shifting acquisition mode. Active stabilization mitigates motion blur effects due to platform instability and enables the adoption of advanced Time Delay Integration (TDI) techniques for SNR improvements. The FOPAC project incorporates the implementation of real-time onboard 2D image correlation algorithms to estimate the instantaneous motion of the focal plane and stabilize it. This compensates for the limited attitude control performance of small platforms, which significantly impacts image quality. Focal plane stabilization, capable of compensating for platform jitter—a source of instability—allows for increased exposure times, thereby enhancing the SNR. Alternatively, with the same exposure time, it reduces motion blur, thus improving the Modulation Transfer Function (MTF). The primary activity of the candidate will be to explore and survey different approaches in 2D image correlation and motion estimation, focusing on new algorithms based on AI. The selected algorithm will be accelerated on an FPGA platform for real-time execution.

In collaboration with TDS-Space and the European Space AgencyWeb page:
https://cassano.faculty.polimi.it/Description
Description:
In the field of Earth observation, the digital Time-Delay Integration (TDI) acquisition technique is crucial for enhancing the quality of satellite images. This method utilizes electro-optical payloads to capture sub-stripes or partially overlapping images. By digitally summing the signals encoded in the pixels of different sub-stripes that correspond to the same ground point, it
is possible to reduce uncorrelated noise and significantly increase signal amplitude. This process leads to a substantial improvement in the signal-to-noise ratio (SNR) and, consequently, the overall quality of the image. However, the digital TDI technique requires capturing multiple images of the same sample, thereby increasing the resources needed for data storage and transmission to ground stations. By performing digital TDI operations directly onboard the spacecraft, it is possible to drastically minimize the volume of data to be stored and maximize the efficiency of bandwidth use for downlink.
Digital TDI activity essentially includes image alignment, which is a prerequisite to ensure that the sum of signals occurs exclusively among pixels corresponding to the same ground sample. During the internship at TSD-Space, the candidate will explore various methods for digital image registration, including advanced approaches that incorporate artificial intelligence. The selected algorithm will be accelerated on an FPGA platform for real-time execution, significantly enhancing the effectiveness of the TDI process.

Description:
Digital design verification involves testing and confirming that a digital design or system is correct and functions properly before it is launched or used. The main objective of this process is to find and fix any design errors or bugs, ensuring that the system operates as intended in various conditions and scenarios.
Randomization is commonly used to generate test stimuli for digital verification-based approaches. It begins with constraints specifying the allowed values and utilizes a seed to generate the stimuli. In current industry practice, there is no standard approach to randomization, which often leads to the same constraints producing different stimuli across different simulation engines.
The thesis focuses on defining a portable randomizer that can connect to existing simulation engines, both free and commercial. This randomizer will intercept calls for randomization and deliver unique stimuli based solely on specified constraints and a seed value. The activity will be conducted in collaboration with the digital verification group at Analog Devices in Milan, Italy.

As part of this collaboration, we develop the firmware required for the readout electronics of Cross Delay-Line (CDL) detectors and instrumentation for pump-and-probe time-resolved experiments.
CDL detectors are systems used in synchrotrons for 3D imaging, capable of providing each frame with spatial details at a resolution of tens of micrometers in x-y coordinates, while simultaneously offering time-of-arrival (t) information for each pixel with a precision of a few tens of picoseconds. The main challenge of these systems, besides high resolution, is minimizing dead-time (in the nanosecond range), ensuring the ability to acquire signals spaced only a few nanoseconds apart without degrading image quality.
https://ieeexplore.ieee.org/document/9855502
Pump-and-probe experiments are essential for material analysis. In synchrotrons, a laser is used as the “pump” source to excite the sample, while X-rays from the synchrotron serve as the “probe,” scanning different energy levels. The challenge is detecting the pulses emitted by the tested sample and correctly correlating them with the synchrotron and laser triggers, enabling beamline scientists to perform data analysis.

The road towards autonomous driving expects vehicles will be equipped with more and more heterogeneous sensors (cameras, lidars, radars, sonars) to perceive the surroundings. Cameras and lidars are the golden standard for autonomous driving, providing high-resolution representations of the environment, but they are sensitive to illumination levels and weather conditions (fog, rain,etc).
Radars, instead, are robust to adverse weather conditions, but are typically characterized by low spatial resolution in the description of the environment and they are currently used for limited purpose (emergency braking).
To improve the reliability of the perception of the environment, future autonomous vehicles are expected to mutually cooperate, exchanging local measurements and features to augment perception.
The thesis aims at using artificial intelligence for cooperative perception based on radars. In particular, the goal of the thesis is to investigate novel AI architectures for aligning, synchronizing and fusing radar images generated at the single vehicles. The proposed thesis can be specialized to generic distributed radar networks, e.g., made of drones.

User-Centric IT Sustainability – Balancing Environmental Impact and User Experience in Adaptive Web ApplicationsContact person
MONICA VITALIEmail:
monica.vitali@polimi.itStudy course: Computer Science and Engineering
Description
Description:
The urgent need to reduce environmental impact has driven IT providers to reevaluate the management and allocation of physical resources for applications. While infrastructure-focused solutions have been prioritized, application developers also play a key role in achieving greener IT by designing applications that adapt dynamically to the availability of renewable energy. This flexibility, however, introduces a trade-off between environmental impact and user experience. For instance, a task could be executed in multiple ways, each with a different computational and energy cost, where the optimal version might be selected based on the availability of renewable energy sources. Such a selection, however, could influence the user experience and, subsequently, customer satisfaction.
This thesis seeks to understand this balance by taking a user-centric approach to IT sustainability, investigating which strategies can encourage consumers to actively support sustainable choices. Specifically, we aim to explore two key research questions:
- What factors influence users when they face a trade-off between sustainability and user experience?
- Can heightened sustainability awareness among consumers make them more receptive to minor reductions in user experience?
Our research will involve user studies to identify the actions and types of information that increase users’ willingness to accept slight QoS trade-offs for sustainability gains. By examining user preferences and the impact of sustainability-awareness strategies, this thesis will provide insights into how consumers can be empowered to support greener applications.

Balancing Privacy, Utility, and Sustainability: A Comparative Analysis of Synthetic Data Generation and Traditional Privacy-Preserving TechniquesContact person
MONICA VITALIEmail:
monica.vitali@polimi.itStudy course: Computer Science and Engineering
Description
Description:
Generative AI enables the creation of synthetic datasets that can address privacy concerns in sensitive data contexts, such as healthcare, finance, and social science research. By generating artificial data that mimics real data distributions without disclosing individual data points, these synthetic datasets promise a powerful alternative to traditional privacy-preserving methods like differential privacy and anonymization. However, this approach comes at an environmental cost. The creation and training of generative models require substantial computational resources, leading to significant energy consumption and, consequently, a notable carbon footprint. At the same time, traditional privacy-preserving methods are not without energy demands, particularly when applied to large and complex datasets. Thus, understanding the trade-offs in energy consumption, utility, and privacy risk between these approaches is crucial for sustainable and effective data privacy practices.
The primary objective of this thesis is to conduct a comprehensive comparison of the environmental and practical implications of synthetic dataset generation and traditional privacy-preserving techniques. This study will focus on three key areas: (1) energy consumption, measured through computational load and resource demands; (2) "fit to use," or the utility and fidelity of the datasets in maintaining representational accuracy; and (3) the risk profile, assessing each method’s effectiveness in safeguarding privacy.
The findings of this thesis will contribute to the emerging discourse on sustainable AI by providing data-driven insights into the environmental impact of privacy-preserving data practices. Given the increasing adoption of AI in sensitive fields and the rising concerns over its carbon footprint, this research aims to offer guidance on balancing data utility, privacy, and environmental responsibility.

AI’s Hidden Footprint: What It Really Takes to Power Large Language Models Like ChatGPTContact person
MONICA VITALIEmail:
monica.vitali@polimi.itStudy course: Computer Science and Engineering
Description
Description:
Large Language Models (LLMs) like ChatGPT are increasingly integrated into our daily lives, from assisting with information retrieval and content creation. As their popularity grows, so does the demand for training these models on massive datasets and frequently updating them in response to the evolving nature of knowledge. However, the computational requirements for training and updating LLMs results in considerable energy consumption. This raises concerns over the sustainability of data centers, especially as they strive to achieve carbon neutrality in the coming years.
Unlike traditional machine learning models, LLMs impose a continuous environmental impact that extends beyond the training phase. The inference phase, where models generate responses in real-time to meet high user demand, is similarly energy-intensive, often consuming as much or more power as training due to the computational complexity of each generated response. A balance between LLMs performance and sustainability needs to be studied to mitigate their environmental impact.
This thesis aims to systematically analyze the energy consumption patterns of popular LLMs, identifying key factors that drive their computational and environmental costs. We will evaluate the impact of various fine-tuning techniques on power consumption, investigating the trade-offs between model accuracy, efficiency, and resource demands.
Additionally, this study will develop a predictive model to estimate the energy consumption of both the training and inference phases for LLMs. This model aims to provide actionable insights to model developers and end-users alike, fostering awareness about the environmental footprint of using LLMs and encouraging more sustainable practices in AI deployment. Ultimately, this research will contribute to a better understanding of how we can optimize LLM usage while minimizing their ecological impact, helping to align technological advancement with environmental responsibility.

Empowering Sustainable Applications to Reduce Data Center Environmental ImpactContact person
MONICA VITALIEmail:

Description
Description:
As the demand for computational resources accelerates, the environmental impact of data centers is becoming increasingly significant. Efforts to address this impact have largely focused on infrastructural solutions, such as improving data center cooling efficiency, optimizing hardware, and transitioning to renewable energy sources. However, this infrastructure-centric approach overlooks an essential dimension: application design and development. Applications themselves, if designed with sustainability in mind, can play a pivotal role in reducing resource consumption and enhancing data center efficiency. This thesis proposes a framework that engages application designers and developers in creating adaptive, sustainable applications to contribute to greener, more environmentally-friendly cloud ecosystems.
This research introduces a novel architecture aimed at embedding sustainability features directly into cloud-native application components and provides a pathway for applications to dynamically adapt their workflows in response to environmental and resource constraints, enabling real-time adjustments based on available energy sources, data center load, and sustainability targets.
The proposed framework will focus on integrating sustainability as a core element in the design and development phases. Specifically, we will explore techniques for embedding adaptability features into application components, allowing them to modify their operations based on environmental conditions, such as shifting processing loads during times of low energy availability or optimizing computational intensity during peak periods. This approach moves beyond static, infrastructure-focused sustainability measures, paving the way for applications that can actively contribute to environmental goals.

Description:
Multimodal large language models (MLLMs) were proposed over the last two years to generate text output from a prompt combining different input types, for instance, text and images. If applied to medicine, they are expected to generate new applications to support clinicians, e.g. in the decision-making when a medical doctor needs advice from a more experienced colleague. Some MLLMs specific to the medical domain were developed, like LLaVA-Med, PeFoMed, and Med-Flamingo. However, those MLLMs can only be used for visual question answering but not other tasks, like image segmentation, which is a critical component in clinical practice, facilitating accurate diagnosis, treatment planning, and disease progress monitoring. Segment Anything Model (SAM) was developed as the first foundational model for the segmentation of natural images. SAM automatically generates segmentation masks by selecting a point, drawing a bounding box around objects to segment, or even using a text prompt. SAM was not specifically developed for medical images, e.g., computed tomography scans, which are traditionally more challenging. Initial studies have shown that its performance was lower than that of deep learning models in the segmentation task of medical images. However, the recent release of MedSAM, a fine-tuned version of SAM on an unprecedented quantity and variety of datasets for medical images, outperforming state-of-the-art deep learning models, disrupted the field. Medical SAM 2, based on SAM 2, outperformed deep learning models, SAM-based ones, and even MedSAM in medical image segmentation.
This thesis work aims to combine MLLMs and foundation models like MedSAM/ Medical SAM 2 to build a tool enabling users to type a prompt like “Segment the pancreas” and visualize the segmentation mask. This thesis will build upon a recent research work at the Politecnico di Milano on a fine-tuned MLLM outputting a bounding box for the localization of the pancreas, given a question like “Where is the pancreas”. The automatically generated bounding box could serve as a prompt for MedSAM/Medical SAM 2 to segment the abdominal organs. Since current MLLMs need improvements in the localization of medical organs, the student(s) will need to optimize the MLLM architecture, for instance by replacing the vision encoder with a novel component, like MedNeXt .
