JPEG Compression Algorithm

http://demonstrations.wolfram.com/JPEGCompressionAlgorithm The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily. This Demonstration shows how a two-dimensional discrete cosine transform works on the image blocks during JPEG compression and how the data is degraded by the quantization matrix. Red points in the graphs on the right side display zeros, which are impor... Contributed by: Jakub Serych Audio created with WolframTones: http://tones.wolfram.com
