A set of still image compression algorithms JPEG (Joint Photographic Experts Group) is becoming an international standard. Here we apply a methodology to study the compression obtained by each step of the three-step baseline algorithm chosen by JPEG. We also present our results, observations and analysis on simulating the JPEG sequential baseline system. The primary compression gain comes from run-length coding of zero coefficients. Based on our simulator, a comparison of Huffman coder, arithmetic coder and LZW algorithm is also included.
