    • 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.
    • 一种用于图像数据和去块滤波器的去块滤波方法。 根据图像数据的去块滤波方法和解块滤波器,当完成了基于输入图像数据的水平和垂直方向之一的每个边界的边界强度(BS)值的计算时,可以估计每个边界的BS值 通过使用所计算的BS值,基于与当前选择的方向不同的方向的边界。 此外,根据估计值,根据相应的方向进行解块滤波,从而可以仅基于选定的一个方向的边界的BS值来完全去除滤波。 因此,可以显着地减少去块滤波处理中必需的BS值计算处理,并且因此也可以显着地减少去块滤波器的操作处理所需的时间。
