For a given textured image we define a sequence of graphs {N-s(t)}(s i
s an element of I) (called MRCG), where N-s(t) is the number of 4-conn
ected components with size greater than or equal to s, for the images
thresholded with t. The sequence of graphs are computed in almost line
ar time complexity, where the input size is the number of pixels of th
e 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.
