Abstract
The present disclosure relates to a video encoding/decoding apparatus, and apparatus and method for adaptive overlapped block motion compensation by variable units for same. The apparatus and the method for adaptive overlapped block motion compensation by variable units, according to the present disclosure, when conducting a motion compensation, enable an encoder to perform an adaptive overlapped block motion compensation for a plurality of predetermined scan modes and sampling modes, and enable the encoder to calculate the computation volume occurring in said compensation and residual pixel energy, estimate the performance for each mode based on the calculation, determine an optimum scan mode and an optimum sampling mode, thus enabling a decoder to perform a motion compensation with optimum performance and less computing volume based on the determined mode.
