This is a basic image process course and very interesting to me. I go through most of the chapters, including Introduction to image and video processing, Spatial processing, Image restoration, Segmentation, Sparse modeling, and compressed sensing, and Medical Imaging. I skip three lectures: Image and video compression, Geometric PDEs, and Image and video inpainting. https://www.coursera.org/learn/image-processing/home/welcome
The most attractive topics are using image processing to discover the HIV cell structure and enhance deep brain simulation.
In addition, Hough transform is a very basic and powerful algorithm for image segmentation and discovering structures.
Sparse modeling and compressed sensing is another really important lecture I have to dig deeper later on.
