This paper proposes a parallel schemelalgorithm which is based on statistical analyses to fulfilthe robust segmentation of nature texture image. The whole scheme is constructed as the parallel hierarchical network with the recursive mechanism and formed as multi-layered structure. It has segmented a mixed nature texture images made of two sort of sleepskings with success. The result is satisfied and shows that the algorithm is high effective and practical and can be applied in production as an essential software of computer automation recognition system of leather quality.
