Abstract :
Mixed Raster Content (MRC) coding is an efficient way of coding compound images. The layered model used gives rise to missing data in the foreground and background layers. When using a block-based transform for coding, the usual solution has been to fill in the missing data using some form of interpolation. In this paper we instead present a method using matching pursuit to find the transform coefficients. The presented method gives a gain of up to 1 dB on the tested images, compared to common data filling methods.
