ECE 6357 Advanced Image Processing

A graduate course on the mathematical and algorithmic foundations of (medical) image analysis, from statistical intensity models and segmentation to image registration.

The course works through primary literature and hands-on implementation: translating ideas into mathematical models, implementing them correctly, and understanding why and when they work, or break.

Co-taught with Yihao Liu.
