摘要
低比特率ＪＰＥＧ压缩图象往往产生严重的方块效应。利用小波分析良好的去噪和边缘检测特性，本文提出一种减少ＪＰＥＧ压缩图象中方块效应的有效算法。计算机仿真结果表明，所提算法能有效地改善解码图象的视觉质量。
Low bit rate JPEG compressed images usually demonstrate serious blocking effects.In this paper we introduce an effective algorithm for the deblocking of the JPEG compressed images based on the denoising and edge detection in wavelet domain.The result of computer simulation shows that this algorithm can achieve efficient PSNR improvement and gets satisfactory visual quality of the image.
