Abstract

Abstract A system and method is disclosed for determining a level of similarity among more than one image. Anticipated spatial characteristics of an image are used for automatically identifying segments within the image and for identifying weights to be added to the color characteristics associated with the identified segments. To determine similarity, comparisons are made between weighted color characteristics of corresponding segments of different images. The identified segments have attributes such as size, position and number which are based on the anticipated spatial characteristics of the image. The anticipated spatial characteristics of the image include, among other things, differences in image characteristics that are anticipated at relative positions within the image. Additionally, a standard for representing image data including feature descriptors for color characteristics is disclosed, the color feature descriptor being divided into plural units corresponding to segments within the image identified based on anticipated spatial characteristics therefor.
