Current Projects

Analysis and Visualization of Colon Motility The objective of this project is to develop a computer aided diagnosis tool to detect colon motility disorders by using cine MRI. The necessary image processing consists of breathing motion compensation, colon segmentation and modelling the natural motion of the colon. New algorithms for measuring the isometry of colon extension should be developed. A prototype software has been already implemented and should be improved in terms of usability.

Knowledge Propagation Models for Image Registration To register modalities with complex intensity relationships, we leverage machine learning algorithm to cast it into a mono modal registration problem. This is done by extracting tissue specific features for propagating anatomical/structural knowledge from one modalitiy to an other through an online learnt propagation model. The registration and propagation steps are iteratively performed and refined. For proof-of-concept, we employ it for registering (1) Immunofluorescence to Histology images and (2) Intravascular Ultrasound to Histology Images.
