Abstract	:	The color images were preprocessed using median filter.The preprocessed color image is compressed using DCT. Then zigzag process is applied to the DCT coefficients. The zigzag applied DCT coefficients are then decomposed using Quad tree Decomposition.Encoding is applied to the Quad tree Decomposed image using Fractal method and Runlength Encoding method.Thecompressed image is then decompressed by reversing the whole process to the original color image.Finally the performance of the method is measured by calculating the Compression Ratio and PSNR value.
