ABSTRACT:
The present invention features a method of characterizing texture of an image. The image is interrogated at least twice in accordance with at least two respective spatial threshold rules. A value for each of the interrogations is obtained. A mesotexture index is calculated by dividing the product of the values by the difference thereof. A plurality of resulting mesotexture indices can be used to generate a characteristic curve that uniquely identifies the image. Since the process is not iterative, a plurality of interrogating steps can be performed in parallel.
