Digital images and videos are everywhere these days – in thousands of scientific (e.g., astronomical, bio-medical), consumer, industrial, and artistic applications. Moreover they come in a wide range of the electromagnetic spectrum - from visible light and infrared to gamma rays and beyond. The ability to process image and video signals is therefore an incredibly important skill to master for engineering/science students, software developers, and practicing scientists.   Digital image and video processing continues to enable the multimedia technology revolution we are experiencing today. Some important examples of image and video processing include the removal of degradations images suffer during acquisition (e.g., removing blur from a picture of a fast moving car), and the compression and transmission of images and videos (if you watch videos online, or share photos via a social media website, you use this everyday!), for economical storage and efficient transmission. 

This course will cover the fundamentals of image and video processing.  We will provide a mathematical framework to describe and analyze images and videos as two- and three-dimensional signals in the spatial, spatio-temporal, and frequency domains. In this class not only will you learn the theory behind fundamental processing tasks including image/video enhancement, recovery, and compression - but you will also learn how to perform these key processing tasks in practice using state-of-the-art techniques and tools. We will introduce and use a wide variety of such tools – from optimization toolboxes to statistical techniques. Emphasis on the special role sparsity plays in modern image and video processing will also be given.  In all cases, example images and videos pertaining to specific application domains will be utilized.


  • Introduction, Image and Video Processing vs Image and Video Analysis vs Computer Vision, the electromagnetic spectrum, applications of image and video processing
  • 2D and 3D signals and systems, linear and shift invariant systems (convolution)
  • 2D and 3D Fourier transform, 2D and 3D discrete-Fourier transform, uniform sampling (rectangular, arbitrary geometry)
  • Motion estimation and its applications
  • Image and video enhancement (e.g., edge detection, noise filtering, histogram equalization, inpainting)
  • Image recovery (restoration, super-resolution)
  • Video recovery (restoration, super-resolution)
  • Lossless compression
  • Image compression techniques and standards
  • Video compression techniques and standards
  • Image and video analysis (e.g., 2D and 3D segmentation, anomaly detection, clustering)
  • Sparsity-based advances in image and video processing

老师口音很重……可能是我个人问题,看这个课的时候完全无法集中精力QAQ 还不如看冈萨雷斯的书来的清楚。心塞= =
