符号化装置、復号装置、符号化方法及び復号方法
Document Type and Number:
Japanese Patent JP6770095
Kind Code:
B2
Abstract:
An encoder (100) which achieves further improvements includes: processing circuitry; and memory. Using the memory, the processing circuitry: for each of blocks each including a plurality of pixels, transforms, using a basis, the block into a block including a plurality of transform coefficients; for each of the blocks each including the plurality of transform coefficients, performs at least inverse transform on the block to reconstruct a block including a plurality of pixels; based on a combination of bases respectively used to transform two blocks which neighbor each other and have been reconstructed, determines a filter characteristic for a boundary between the two blocks (Steps S1201, S1202); and performs, on the boundary, deblocking filtering with the filter characteristic determined (Step S1203).
