摘要:
As a prediction vector is set a prediction vector selected from one of a first prediction vector candidate and a prediction vector candidate in accordance with an encoding cost. The prediction vector candidate is a prediction vector candidate selected from one of a second prediction vector candidate and a third prediction vector candidate in accordance with a predictive accuracy of the third prediction vector candidate. The first prediction vector candidate is a median of motion vectors assigned to respective partitions surrounding a target partition. The second prediction vector candidate is a motion vector assigned to a partition adjacent to a left side of the target partition. The third prediction vector candidate is a motion vector assigned to a collocate partition identical in location to the target partition of a decoded frame.
摘要:
A loop filter section according to an embodiment of the present invention includes: a BF section selectively acting on a block boundary of an image processed block by block; and an adaptive filter section including a first linear filter section that acts on an input image to be supplied to the BF section and a second linear filter section that acts on an output image of the BF section. The adaptive filter section performs addition of an output image of the first linear filter section and an output image of the second linear filter section to output a result of the addition.
摘要:
The present invention relates to a device including (i) a spatial-direction prediction vector generating section (191) which calculates a first prediction vector group by referring to a first motion vector group made up of motion vectors for encoded partitions, (ii) a temporal-direction prediction vector generating section (192) which calculates a second prediction vector group by referring to a second motion vector group made up of motion vectors for partitions around a collocated partition, and (iii) a prediction vector selecting section (194) which assigns, to the target partition, a prediction vector selected from prediction vectors in the first prediction vector group or from prediction vectors in the second prediction vector group based on variation of the first motion vector group and variation of the second motion vector group.
