Key-point Matching for Non-Rigid Endoscopic Image Streams
Deformable key-point-based image matching is the task of finding correspondences between key points detected in two or more images [1,2] that are related by an unknown non-rigid motion. This task is particularly difficult for very large elastic deformations, such as the images obtained from endoscopic videos . In this project, we will study this type of images and evaluate the most relevant strategies (from classical descriptors to more novel CNN-based approaches ) to match non-rigid images, analyzing the failure cases and proposing a solution. This master thesis will be carried on in the Institut de Robòtica i Informàtica Industrial, at the Universitat Politècnica de Catalunya (under direction of Dr. Antonio Agudo and Dr. Francesc Moreno).
Candidates with a background in mathematics, medical image and good programming skills (Matlab/C++) are particularly encouraged to apply.
