161C - Digital Signal Processing II



This course provides an introduction to image processing and computer vision. We start from the basics of image formation (cameras, light, color), then cover the fundamental concepts in 2D signal processing (2D convolutions, Fourier transforms, etc) and low-level vision (edges, texture), and finally move on to higher level problems such as motion analysis, image segmentation, image classification and retrieval.

Note: There are various editions of the book. The numbers of problems from
the book may not be those of your version. In general, you can tell
which problem we are talking about, by hints, notes, etc. If you don't,
make sure to ask.

Only the computer problem of each assignment will be graded. You should not turn in the other problems. HW should be submitted to the TA.
