Abstract |
|
Image compression is a process to remove the redundant information from the image so that only essential information can be stored to reduce the storage size, transmission bandwidth and transmission time. The essential information is extracted such that it can be reconstructed without losing quality and information of the image. In this paper, image compression has been done by the method using DCT and DWT transforms. The comparison of the this combined DCT + DWT method has been done with the previous techniques available i.e. DCT and DWT and it was found that the results of the proposed algorithm are much better than alone DCT and DWT algorithms in terms of peak signal to noise ratio (PSNR), mean square error (MSE) and compression ratio (CR). |
