Abstract: The concepts of image compression are explained using the mathematical equations of DCT. The analysis of JPEG standard is based on discrete cosine transforms (DCT). In the JPEG standard, DCT played the important role of separating information by using different frequencies. The Compression was achieved through quantization and coding. Image compression is a technique by which the amount of data required to represent a digital image is reduces and hence this can minimize such type of problems. JPEG image format is based on Discrete Cosine Transformation (DCT), quantization and encoding process. Enhancing the efficiency of JPEG is hardly to develop the algorithm of quantization and coding. Finally, the JPEG compression encoder established, and the performance of compressed image presented.
