Abstract
A deblocking filtering method for image data and a deblocking filter. According to the deblocking filtering method for image data and the deblocking filter, when computation of Boundary Strength (BS) values for each boundary based on one of horizontal and vertical directions from input image data is completed, it is possible to estimate BS values for each boundary based on a direction different from the currently selected direction by using the computed BS values. Further, deblocking filtering is performed based on corresponding directions according to the estimated values, so that the deblocking filtering can be completely performed with only a BS value of boundaries based on a selected one direction. Consequently, a BS value computation process necessarily required in a deblocking filtering process can be considerably reduced, and thus time required in the operation process of a deblocking filter can also be considerably reduced.
