摘要：A signal adaptive filtering method for reducing blocking effect and ringingnoise, a signal adaptive filter, and a computer readable medium. The signal adaptive
filtering method capable of reducing blocking effect and ringing noise of image datawhen a frame is composed of blocks of a predetermined size includes the steps of: (a)generating blocking information for reducing the blocking effect and ringing informationfor reducing the ringing noise, from coefficients of predetermined pixels of the upperand left boundary regions of the data block when a frame obtained by deconstructing abitstream image data for inverse quantization is an intraframe; and (b) adaptively filteringthe image data passed through inverse quantization and inverse discrete cosinetransform according to the generated blocking information and ringing information.Therefore, the blocking effect and ringing noise can be eliminated from the imagerestored from the block-based image, thereby enhancing the image restored fromcompression.
