Abstract

In one instance, the method of these teachings for identifying/accessing color related information includes generating, for a color image, a number of color clusters in a color space (e.g. RGB, HSV, CYMK, LUV, etc.), assigning each pixel in the image to one of the clusters, and separating the information identified with the color of the cluster; thereby identifying/accessing the color related information.

Claims

1. A method for identifying/accessing color related/indicated information, the information not being a color itself, the method comprising the steps of:

generating, for a color image, utilizing a clustering component, a number of color clusters in the color space;

assigning each pixel in the color image to one of the color clusters; and

separating the information indicated by color in the color clusters;

color related/indicated contextual information being identified/accessed.

2. The method of claim 1 further comprising the step of:

obtaining, after assigning each pixel in the color image to one of the color clusters, a number of binary images, each binary image containing information from one color cluster;

binary images in the number of binary images being obtained by means of a computer usable medium having computer readable code that causes at least one processor to implement the method.

3. The method of claim 2 further comprising the step of subsampling the color image;

and wherein, in the step of generating a number of color clusters, the color clusters are generated for the subsampled color image.

4. The method of claim 2 further comprising the step of:

filtering at least one binary image from the number of binary images.

5. The method of claim 1 wherein the step of assigning each pixel in the color image to one of the color clusters comprises the steps of:

obtaining, by means of a computer usable medium having computer readable code that causes at least one processor to implement the method, a cluster centroid for each color cluster;

assigning each pixel to one of the color clusters based on a distance from each pixel to the cluster centroid of each color cluster.

6. A system for identifying/accessing color related/indicated information in a color image, the information not being a color itself, the system comprising:

an image acquisition device acquiring the color image;

an image processing subsystem comprising;

a clustering component generating a plurality of color clusters in a color space from the color image;

at least one processor; and

at least one computer usable medium having computer readable code embodied therein, the computer readable code causing said at least one processor to;

assign each pixel in the color image to one of the color clusters; and

separate the information indicated by color in the color clusters;

color related/indicated contextual information being identified/accessed.

7. The system of claim 6 wherein said clustering component comprises computer readable code embodied in said at least one computer usable medium, said computer readable code causing said at least one processor to generate said plurality of color clusters in the color space from the color image.

8. A computer program product comprising a computer usable medium having computer readable code embodied therein;

said computer readable code causes at least one processor to;

assign each pixel in the color image to one of the color clusters; and

separate the information indicated by color in the color clusters;

color related/indicated contextual information being identified/accessed.

9. The computer program product of claim 8 wherein said computer readable code also causes said at least one processor to:

obtain, after assigning each pixel in the color image to one of the color clusters, a number of binary images, each binary image containing information from one color cluster.

10. The computer program product of claim 9 wherein said computer readable code also causes said at least one processor to:

subsample the color image; and

wherein, in generating a number of color clusters, said at least one processor generates the color clusters in the subsampled color image.

11. The computer program product of claim 9 wherein said computer readable code also causes said at least one processor to:

filter at least one binary image from the number of binary images.

12. The computer program product of claim 8 wherein said computer readable code also causes said at least one processor to:

obtain a cluster centroid for each color cluster;

assign each pixel to one of the color clusters based on a distance from each pixel to the cluster centroid of each color cluster.
