Abstract Recent deblocking techniques are based on spatial filtering. We present a new deblocking technique based on temporal filtering of spatially aligned frames. This approach is used in an H.264/AVC coding environment. The algorithm estimates the ideal amount of frames used for temporal filtering at the encoder side. In that way it is assured that the receiver is presented with the best possible visual quality in terms of structural similarity. Theoretical consideration of the problem proves the concept of the new approach. Experimental evaluation shows that the new temporal deblocking filter significantly improves visual quality and reduces bit rate compared to common H.264/AVC deblocking by up to 18%.
