Moreover  the detecting function is applied to extract the adjacent two blocks with the blocking artifact and is combined with the DCT-based adaptive post-processing technique [1] for reducing the blocking artifacts of the decoded image. The new technique is used to process JPEG compressed image and results show improvement in both effective DCT operation and peak-signal to noise ratio (PSNR) with preserving the image quality.   Multiscale asymptotic expansion and a post-processing algorithm for second-order elliptic problems with highly oscillatory coefficients over general convex domains 期刊论文  OAI收割 JOURNAL OF COMPUTATIONAL AND APPLIED MATHEMATICS, 2003, 卷号: 157, 期号: 1, 页码: 1-29 作者:  Cao, LQ;  Cui, JZ;  Luo, JL   |  收藏  |  浏览/下载：21/0  |  提交时间：2018/07/30 multiscale asymptotic analysis  second-order elliptic type equation  highly oscillatory coefficient  finite element method  post-processing technique
