XEOS : Détection par IA de défauts sur des photographies aériennes

XEOS : Détection par IA de défauts sur des photographies aériennes

Principales activités du partenaire :
XEOS Imagerie est une entreprise spécialisée en photographie aérienne, relevés lidar et cartographie par intelligence artificielle. Elle a développé une grande expertise en cartographie par intelligence artificielle notamment à partir de nuages de points lidar en 3 dimensions et de photographie aérienne.

Problématique et avantages escomptés du projet :
La validation des reconstructions 3D des bâtiments est facilitée par l’examen de photographies aériennes dans les mêmes zones. Celles-ci permettent de mettre en contexte les surfaces des bâtiments et autres structures détectées. Elles permettent aussi d’identifier des problèmes ayant potentiellement des conséquences sur les reconstructions 3D et leur interprétation.
La présence de défauts d’acquisition dans la photographie aérienne réduit la qualité d’interprétation ou rend la photo inutilisable. La détection manuelle de ces défauts dans des milliers d’images prend du temps et est laborieuse. Il serait utile d’automatiser et d’optimiser ce processus. Plusieurs approches s’offrent à nous.
La définition du problème de la détection d’objets se divise essentiellement en deux parties distinctes : où se trouvent les objets dans une image donnée (localisation des objets) et à quelle catégorie appartient chaque objet (classification des objets). Par conséquent, les pipelines des modèles traditionnels de détection d’objets peuvent être divisés en trois étapes : sélection de la région informative, extraction des caractéristiques et classification. Les réseaux de neurones permettent d’effectuer ces trois étapes en même temps.
XEOS Imagerie possède déjà à l’interne une grande expertise en programmation en intelligence artificielle mais désire s’entourer de plusieurs stagiaires afin d’augmenter sa capacité de développement de produits.

Deformable Image Registration for Multimodal Radiotherapy Treatments in Gynaecological Cancers: External Beam and Brachytherapy

The Radiation Medicine Program at the Princess Margaret Cancer Centre delivers curative radiation therapy (RT) to cancer patients, including those with gynecological cancers, using a combination of external beam radiation therapy (EBRT) and brachytherapy (BT). A key clinical challenge is the accurate accumulation of radiation dose delivered across these modalities. Current methods rely on deformable image registration (DIR), which is hindered by large uncertainties due to anatomical changes caused by the BT applicator, variable bladder and rectum filling, and tumor shrinkage during treatment (Fu et al., 2023). These limitations reduce the accuracy of longitudinal dose accumulation and compromise treatment effectiveness. This project addresses that challenge by developing deep generative models to remove BT applicators from MR images, enabling accurate DIR and dose mapping between EBRT and BT sessions. The partner organization will benefit clinically by improving treatment precision and enabling better-informed re-irradiation strategies. Socially, the project supports safer, more effective cancer therapy, while economically, it may reduce planning errors and treatment complications, ultimately improving healthcare resource efficiency. By advancing AI-driven radiotherapy tools, this project also enhances the partner’s leadership in integrating machine learning into clinical cancer care.

Monitoring hair surface chemical modifications using atomic force microscopy

Since the beginning of recorded time, humans have been developing ways to make themselves more beautiful or
otherwise change their appearance. The hair-care industry itself has a huge global economic power: its estimated total
value is $47B annually. However, beauty does not come without a price: methods currently being used for hair
colouring and styling damage hair greatly. More importantly, they involve treatments that have negative effects on
human and environmental health.
To reduce the toxicity of hair-care treatments, SLI Beauty is developing new hair-surface chemical modification
techniques. I have partnered with them to bring my expertise at biophysical characterization to assess the success of
these surface modifications, and to develop new treatment modalities. With dedicated time spent onsite in the SLI
Beauty labs, I have the opportunity to bring my critical skills to help develop marketable products for this expanding
company.

Homo/Hetero Hybrid Dyadic Systems for Artificial Photosynthesis

Climate change is one of the main concerns of our society and is closely linked to the large consumption of fossil fuels and their associated carbon emissions. An appealing alternative is the production of hydrogen from water, powered by sunlight. Our project aims to develop a first family of efficient hybrid dyadic catalysts for this purpose. These catalysts will combine a molecular light-absorbing unit, known as photosensitiser (PS), anchored to the surface of a metallic nanoparticle (NP), which will act as the catalyst. A first-of-its-kind hybrid dyadic system was recently developed in a collaborative work between the University of Montreal and the Autonomous University of Barcelona. In this project, we will address the issues found in the first-generation catalysts. For this, we will design tailored PSs with improved properties, which we expect to increase the hydrogen production. In addition, we will work towards a second-generation of hybrid dyadic systems able to perform overall water splitting upon sunlight irradiation. In this way, both institutions will work together in expanding our knowledge of this unexplored field of research, which will enable the rational design of new efficient hybrid materials.

Awareness to Action: Understanding Employers’ Motivations for Building Disability Confidence

This community based participatory research project will seek to understand the motivational, capability, and opportunity factors that enable SMEs to hire people with disabilities, and to investigate what kinds of messaging strategies are effective in encouraging employers to develop their capacity for disability inclusive hiring. The project will be conducted in collaboration with the Canadian Council on Rehabilitation and Work (CCRW – a national disability employment non-profit service provider) to enhance their advocacy efforts by informing effective communication strategies, including how to design messages that are persuasive to employer audiences. Methods will include a literature review, in-depth qualitative interviews with disability inclusive SME employers across Canada and co-designing recommendations for the development of employer-informed marketing and communication tools for CCRW to use to motivate disability inclusive hiring among other SMEs across Canada. The findings from this research will allow the organization to reach new employers by communicating the value of disability inclusion, and the benefits of engaging CCRW for support and resources on workplace inclusion. The findings from this project will benefit Canada by developing evidence-informed employment service provision to help close the gap between the employment demands of SMEs and the supply of potential workers with disabilities.

Improving the efficiency of the supersonic binary fluid ejector using computational fluid dynamic modeling – Year two

The only commercially available technology that directly uses thermal energy to produce cooling is absorption chillers,
which are not economical for small-medium scale buildings (<100,000 sq.ft.) and suffer from serious performance limitations. May-Ruben Thermal Solutions (MRTS) is developing a novel Binary Fluid Ejector (BFE) that will provide a high-performance, economic, scalable, thermally-driven heat pump and refrigeration cycle. Early applications include space cooling/heating for residential and commercial buildings, providing economic savings and GHG reductions. MRTS is currently constructing a laboratory BFE prototype. The proposed project includes research needed to support the development of an alpha prototype which consists of a closed-loop recirculating BFE heat pump system, including 3-D computational fluids dynamic (CFD) to be performed by the candidate. This modeling work will enable the design of geometrically optimized ejectors that maintain their performance when used in applications with higher temperature differences, such as space cooling, where traditional ejectors rapidly loose efficiency.
