英文摘要 | This work describes a medical image coder based on a hybrid wavelet-residual discrete cosine transform (DCT) algorithm. In the method, each image is transformed by wavelet and discarded some low-energy coefficients. We use the discrete cosine transform for encoding the residual image due to its good performance on difference. And the image will be gathered from what is reconstructed by coefficients of wave let and DCT when using the proposed algorithm. Experimental results show that the proposed technique improves the quality of the reconstructed image in both PSNR and perceptual result when compare to JPEG at the same bit rate. |
