基于分块的压缩重建方法
Compression reconstruction methods based on block
摘要
Abstract
Image compression and reconstruction are a hot Copic in image processing.This paper presents a new reconstruction method based on block.The new method firstly divides the image into the same blocks according to a certain rule. Then it applies the SL0 algorithm to every block, which is reconstructed successively.Finally,we scrape up the whole from blocks.The size of the block can affect the time and quality of the reconstruction image.If the size of the block is too small that blocking artifacts do harm to the quality of the reconstruction image.In this paper,the Wiener filtering is employed to improve the quality of the reconstruction image which has many small blocks.The simulation results show that the method has the advantages of the reconstruction time and the compression quality.关键词
