Abstract: This paper covers the analysis process of JPEG (joint picture expert group) standard which is based on the technique called discrete cosine transform (DCT).In this process, DCT, is used for the separating information by different frequencies. Using the processes quantization and encoding the Compression is achieved. There were various algorithms of fast DCT was analyzed. These could be finding efficient for JPEG encoding process. Therefore, it is very hard or difficult to develop algorithm of quantization and coding for enhancing the efficiency of JPEG encoding process. At last, the compression encoding process that was based on JPEG is discussed in detail.
