Abstract
A generic spatially scalable shape encoding apparatus and method for deriving shape information for chrominance components from luminance component. The present generic spatially-scalable shape encoding applies a series of subband (e.g., wavelet) filters to obtain N-levels of wavelet decomposition for the texture information of both luminance and chrominance components. The application of the corresponding subsampling filters of said subband filters is applied in a manner such that the shape of the chrominance can be derived from the shape of the luminance at the same spatial layer.
