Patent ID: 8498473

Claim:
A computer-implemented method for comparing similarity between images, comprising: receiving, at a first computer, a base image and a selected portion of the base image as a basis for image comparison, the base image corresponding to a web page as rendered by a first browser; receiving, at the first computer, at least one analysis image, the at least one analysis image corresponding to the web page as rendered by at least a second browser different from the first browser; determining a portion of the at least one analysis image corresponding to the selected portion of the base image; determining color information for the selected portion of the base image and for the corresponding portion of the at least one analysis image; determining a color score by comparing the color information of the selected portion of the base image to the color information of the corresponding portion of the at least one analysis image; and determining, at the first computer, a similarity between the base image and the at least one analysis image based on the color score, the similarity reflecting a degree to which the base image and the at least one analysis image are identical.
