Abstract:
An image coding method for coding an input image per block to generate a coded image signal includes: predicting for each prediction unit which is an area obtained by partitioning a target block to generate a prediction image of the target block; comparing a transform unit which is an area obtained by partitioning the target block and is a processing unit for frequency transform with the prediction unit, to detect part of a boundary of the prediction unit, the boundary being located within the transform unit; performing boundary filtering on the detected part of the boundary in the generated prediction image; calculating a difference between a filtered prediction image and the input image to generate a difference image of the target block; and performing frequency transform on the difference image for each transform unit.

Claim (Index 1):
A non-transitory computer-readable recording medium storing a program for decoding a coded image signal obtained by coding an image per block, the program when executed by a computer performing steps comprising:\n receiving the coded image signal; performing inverse frequency transform on transform units (i) each of which is an area obtained by partitioning a target block and (ii) each of which is included in the coded image signal, to generate a decoded difference image of the target block; performing prediction process on prediction units (i) each of which is an area obtained by partitioning the target block and (ii) each of which is included in the coded image signal, to generate a prediction image of the target block; adding the prediction image and the decoded difference image, to generate a decoded image of the target block; and performing a filtering process on a boundary of the prediction unit in the generated decoded image, when the boundary of the prediction unit is located within a transform unit, the transform unit being an area obtained by partitioning the target block and being a processing unit for frequency transform.
