Video encoding/decoding apparatus, Deblocking filter and deblocing filtering method, and Recording Medium therefor

摘要

A deblocking filtering apparatus according to an embodiment of the present invention includes a moving picture encoding / decoding apparatus, a deblocking filtering apparatus and method, and a recording medium, A boundary strength determination unit; The optimum direction is selected on the basis of the amount of change of the pixel value between pixels corresponding to each direction among a plurality of predetermined directions for each pixel of the boundary of the subblock, A filtering direction determination unit for determining a most selected direction among a plurality of optimal directions in a filtering direction of the corresponding sub-block; And selecting pixels to be filtered based on the determined filtering direction for each pixel in the boundary of the sub-block, determining whether to filter the determined filtering direction according to a relationship between pixel values of the selected pixels, And a filtering unit that performs filtering on the selected pixels in the determined filtering direction according to whether or not filtering is performed, thereby improving the elimination performance of block distortion and reducing the amount of computation.;Image, compression, encoding, decoding, deblocking artifact, filter, edge, oblique line, computation amount
