Abstract
A processor-based method and a system are provided which are configured to regressively cluster pixels of an image and segment the image based upon the step of regressively clustering.
Claims23
A processor-based method, comprising:
- regressively clustering pixels of an image with respect to a color model characterizing the image by regressing functions that correlate pixels having an attribute of similar value with respect to a first primary color of the color model and clustering pixels of the image into distinct groups based upon the regressed functions;
- and
- segmenting the image based upon said regressively clustering such that retrievable segments are formed within a memory coupled to a micro-processor conducting the processor-based method.
A tangible computer readable storage medium having instructions for causing a computer to execute a method, comprising:
- determining a number of segments by which to distinguish portions of an image;
- generating a set of functions, for each segment, that correlate pixels of the image having an attribute of similar value relative to a color model, wherein each of the set of functions is based relative to a different primary color of the color model characterizing the image;
- regressing, for each segment, the set of functions;
- clustering pixels of the image into different groups based upon the regressed sets of functions;
- and
- repeating said regressing and said clustering sequentially.
3 more elements
A system, comprising:
- an input port configured to receive an image;
- and
- a processor configured to:
- regress functions that correlate pixels of the image having an attribute of similar value relative to a color model, the functions being regressed with respect to different primary colors of the color model characterizing the image;
- cluster the pixels into distinct segments using the regressed functions;
- and
- reiterate said regress and cluster.
4 more elements
A system, comprising:
- a first means to receive an image;
- and
- a second means for regressively clustering pixels of the image with respect to a color model characterizing the image to produce distinct segmentations of the image by regressing functions that correlate pixels having an attribute of similar value with respect to a first primary color of the color model and clustering pixels of the image into distinct groups based upon the regressed functions.
