Block lossy compression image ignores the inter-block correlation, Reconstruction would have a blocking effect, the paper presents a airspace Adaptive Deblocking Algorithm. To block the edge of rational use of the direction of adaptive filtering, in order to weaken the block effect. According to block the internal activity of the image block is divided into a flat block and texture block 2 categories, the use of airspace based on the variance detection methods to detect the flat block, and a flat block adjacent block edge adaptive smoothing. Experimental results show that the algorithm effectively blocking go except, to some extent, improve the signal to noise ratio, the algorithm is simple and better robustness.
