Image Signal Processing

Image Signal Processing. Instructor: Prof. A. N. Rajagopalan, Department of Electrical and Electronics Engineering, IIT Madras. This course spans both basics and advances in digital image processing. Starting from image formation in pin-hole and lens based cameras, it goes on to discuss geometric transformations and image homographies, a variety of unitary image transforms, several image enhancement methods, techniques for restoration of degraded images, and 3D shape recovery from images.
