Abstract

For a given textured image we define a sequence of graphs {Ns(t)}s∈I (called MRCG), where Ns(t) is the number of 4-connected components with size ≥s, for the images thresholded with t. The sequence of graphs are computed in almost linear time complexity, where the input size is the number of pixels of the image, using only integer arithmetic. The MRCG is a multiresolution representation, which is very useful for texture characterization. Its properties as a texture characterizer are analyzed and demonstrated.
