Abstract
A video encoding apparatus, which encodes a digital video provided as a video signal of a pixel value space subjected to spatial and temporal sampling, includes a nonlinear video decomposition unit, a structure component encoding unit, and a texture component encoding unit. The nonlinear video decomposition unit decomposes an input video a into a structure component and a texture component. The structure component encoding unit performs compression encoding processing on the structure component of the input video a decomposed by the nonlinear video decomposition unit. The texture compression encoding unit performs compression encoding processing on the texture component of the input video a decomposed by the nonlinear video decomposition unit. Such an arrangement provides improved encoding efficiency.
