Abstract
Abstract A method for characterizing an image where a number of test areas of predefined shape and size are located on the image. The color or the texture of the image over each of the test areas is quantified. The image can be characterized by statistical descriptions of the frequency distribution of color or texture of the test areas.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
93 words
A method for characterizing an image comprising the steps of: (a) defining a spatial structural element including a plurality of picture elements; (b) delineating on said image a plurality of test areas corresponding to said spatial structural element, wherein the selection of said test areas is not based upon the content of the image associated with said test areas; (c) quantifying the color of each of said test areas on said image; and (d) characterizing said image based upon the distribution of the population of said test areas as a function of color.
Claim 2
Independent Claim
93 words
A method for characterizing an image comprising the steps of: (a) defining a spatial structural element including a plurality of picture elements; (b) delineating on said image a plurality of test areas corresponding to said spatial structural element, wherein the selection of said test areas is not based upon the content of the image associated with said test areas; (c) quantifying the color of each of said test areas on said image; and (d) characterizing said image based upon the distribution of the population of said test areas as a function of color.
Claim 3
Dependent Claim
28 words
The method of claim 1 wherein the color of each of said test areas is quantified as at least one of the mean color and the representative color.
Claim 4
Dependent Claim
29 words
The method of claim 1 wherein the color of each of said test areas is quantified as the mean of each of the red, green, and blue color intensities.
Claim 5
Dependent Claim
28 words
The method of claim 1 comprising the further step of characterizing said image by the distribution of the population of said test areas as a function of color.
Claim 6
Independent Claim
86 words
A method for characterizing an image comprising the steps of: (a) defining a spatial structural element including a plurality of picture elements; (b) delineating on said image a plurality of test areas corresponding to said spatial structural element; (c) testing the homogeneity of the color of each of said test areas; (d) quantifying the color of each of said test areas having a sufficiently homogeneous color; and (e) characterizing said image by the distribution of the population of said test areas as a function of color.
Claim 7
Independent Claim
86 words
A method for characterizing an image comprising the steps of: (a) defining a spatial structural element including a plurality of picture elements; (b) delineating on said image a plurality of test areas corresponding to said spatial structural element; (c) testing the homogeneity of the color of each of said test areas; (d) quantifying the color of each of said test areas having a sufficiently homogeneous color; and (e) characterizing said image by the distribution of the population of said test areas as a function of color.
Claim 8
Dependent Claim
20 words
The method of claim 5 wherein the color is each of said test areas is quantified as the mean color.
