2023 Fall: 数字图像与数字视频处理

Written by  |  28/08/2021 - 08/48

Course Description:

Image is an essential form of information representation and communication in modern society. Nowadays, billions of images are generated daily in various applications ranging from photography, entertainment, education, and defense to medicine. Digital image processing provides fundamental modeling and computing solutions for image capture, filtering, segmentation, quantization, resampling, super-resolution, and compression solutions. 

In this introductory course on digital image processing, we cover the basics in both theory and practice of image sampling, quantization, filtering, and deep convolution and their applications in segmentation, super-resolution, classification, and compression.

Upon completion of the course, students should be able to understand the current state of the art in the image processing area, have practical programming and system skills to address these problems, and have the basis for future research exploration and industry careers in this area.
