Detection of Homogeneous Regions by Structural Analysis

A method is proposed for partitioning input scenes into regions in which selected picture properties are regarded as uniform. In this procedure, usual statistical methods of in­ specting average gray levels are not used, but the uniformity of complex picture proper­ ties such as shapes, sizes or arrangements of subpatterns in the pictures is examined by a structural analysis. The analyzing process is controlled by a supervisor which gives the order of changing the depth of interest in each picture property, and successive parti­ tioning of the pictures is made toward an interpretable goal partition.
