چکیده

In this paper, modeling of optimized Discrete Cosine Transform (DCT) with reduced hardware and implementation of JPEG Image compression in MATLAB is presented. DCT is the heart of the JPEG image compression. The computation of DCT is hardware intensive and power consumption is also very high. In JPEG Image Compression pipeline, a quantizer follows the DCT. Such structural pipeline is advantageous for reduced complexity in the entire JPEG compression/encoding. We compute DCT with no multipliers without any scaling operation and this scaling operation is absorbed in the JPEG compression flow itself. Performance of our implementation is also presented.

High performance DA - based DCT , DWT and DHT

Abstract: Thee transform coding is a major block in any compression technique. Transform coding helps in decorrelating the input data and for energy compaction which are required to implement compression. DCT is standard transform used in JPEG image compression standard and DWT is used in JPEG2000image compression standard. The DHT is a transform which provides flexibility in terms of hardware ...
