A signal adaptive filtering method for reducing blocking effect and ringing noise, a signal adaptive filter, and a computer readable medium and The signal adaptive filtering method capable of reducing blocking effect and ringing noise of image data when 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 information for reducing the ringing noise and from coefficients of predetermined pixels of the upper and left boundary regions of the data block when a frame obtained by deconstrucing a bitstream image data for inverse quantization is an intraframe; and b) adaptively filtering the image data passed through inverse quantization and inverse discrete cosine transform according to the generated blocking information and ringing information. ?? Therefore the blocking effect and ringing noise can be eliminated from the image restored from the block-based image and thereby enhancing the image restored from compression. IMAGE
