Texture Region Growing Based Upon a Structural Model of Texture

Abstract

In this paper the problem of texture boundary formation is approached by a region growing technique that is based upon a structural model of texture. Region growing is based upon similarities among texture elements and upon the spatial proximities of these elements. The region grower itself is a global algorithm that makes use of a minimal spanning tree of what is called the associated texture graph of a texture. A primary advantage of the method is that the texture regions are self-organizing in the sense that no artificial windows need be superimposed over the source textures. While the region described in this paper uses extrema-based texture elements, the application to other types of elements is straightforward.
