Abstract - Digital pictures area unit typically employed in many domains. great amount of information is critical to represent the digital pictures that the transmission and storage of such pictures area unit long and unworkable. thence the knowledge within the pictures is compressed by extracting solely the visible components. usually the compression technique will scale back the storage and transmission prices. throughout compression, the dimensions of a graphics file is reduced in bytes while not distressful the standard of the image on the far side a suitable level. many ways like separate trigonometric function remodel (DCT), DWT, etc. area unit used for pressing the photographs. But, these ways contain some obstruction artifacts. so as to beat this problem and to compress the image with efficiency, a mix of DCT and shape compression techniques is projected. DCT is utilized to compress the colour image whereas the shape compression is utilized to evade the repetitive compressions of analogous blocks. Analogous blocks area unit} found by exploitation the geometrician distance measure. Here, the given image is encoded by means that of Huffman secret writing technique. The implementation result shows the effectiveness of the projected theme in pressing the colour image. Also, a comparative analysis is performed to prove that our system is competent to compress the photographs in terms of Peak Signal to Noise magnitude relation (PSNR), Structural Similarity Index (SSIM) and Universal Image Quality Index (UIQI) measurements. we tend to introduce a brand new thanks to use shape writing for compression, supported the parallel use of a shape encoder and a DCT encoder. the 2 encoders area unit given the complementary roles to capture the knowledge of edge and sleek variation, and therefore the data of detail severally. we tend to show the advantage of exploitation this hybrid writing theme over the employment of a shape encoder alone, or a DCT encoder alone. This writing theme is additionally the occasion to demonstrate a brand new idea of writing by nonlinear feature separation supported regular and uniform algorithms, appropriate for time period VLSI implementation
