JPEG 2000 encoding and decoding, DCT, quantization, encoding entropic, huffman, arithmetique, wavelets coefficients

jpeg coder and decoder with out using block proc function.Reading the image into 8x8 blocks and apllied the DCT transform and quantization using quantization tables.After that seperation of DC and AC coefficients and I applied the DPCM for DC coeffci

The aim of this application is to implement scalable mpeg type compression by varying DCT coefficients and finding minimum number of DCT coefficients that can give minimum acceptable quality.. This application only works for gray scale.
