Block Matching Algorithms for Motion Estimation This project contains the project report and source code by Aroh Barjatya for Digital Image Processing Class at Utah State University.

Since then the author has moved on to another research area and is not longer active in this field. Thus, please do not write any questions for help. *Everything* needed to understand the code and techniques are either written as part of comments within the code, or within the PDF file. I truly hope that this code is as much help to you as it was fun for me to write! Aroh Barjatya
