Paper Abstract

We present a method for analyzing and resynthesizing inhomogeneously textured regions in images for the purpose of advanced compression. First the user defines image blocks so that they cover regions with homogeneous texture. These blocks are each transformed in turn. For the transform we use the so called Principle Component Analysis. After the transform into the new domain we statistically analyze the resulting coefficients. To resynthesize new texture we generate random numbers that exactly meet these statistics. Using the inverse transform the random coefficients are finally transformed back into the spatial domain. The visual appearance of the resulting artificial texture matches the original to a very high degree.
