Abstract
Digital video imagery is deblocked as a function of horizontal and/or vertically oriented pixels that share a common attribute (such as a corresponding pixel value). In particular, a deblocking filter can be selected from amongst a plurality of candidate deblocking filters as a function of the presence of pixels that are both adjacent to one another and that are substantially similar to one another. The selected deblocking filter can be applied as a function, at least in part, of a respective center of the pixels that are both adjacent and similar to one another. In one embodiment, luminance information is deblocked pursuant to a process that is different from a deblocking process that is used with chrominance information.
