Abstract
A method of classifying images based on elliptical color models is utilized in a number of applications. One or more color models are generated from a set of images with a region of interest. Then, sets of images are utilized for training. One set of images has regions of interest, and the other set of images is without regions of interest. By utilizing the two sets of images, a maximum difference between the sets is achieved, so that a color model is most representative of the object desired. Then using the optimal color model, a collection of images are able to be searched, and images are retrieved based on the probability that the images contain the desired object.
