The file PatternRecognition.rar contains 5 projects and the corresponding source code implementing the algorithms used for pattern recognition in still images, audio and video files. It contains: i) Discrete Cosine Transform in c# ii) face detection algorithm in c++ iii) speech recognition algorithm in c++ iv) algorithm to identify similar images in c++ v) Video playing and processing algorithms in c#.



These projects were compiled from the CodeProject websites. The detailed descr iption can be found in the Readme.txt file.-Content of　Readme.txt



The decompressed folder　PatternRecognition　contains 5 subfolders including the source codes

that implements the computer algorithms for intelligent processing of still images, audio and video

information. They were collected and compiled from the　codeproject　a comprehensive website for source code sharing

among software developers and researchers. The programs were implemented in c++ and c#.
