Abstract
A system and method for segmenting an image. The system and method include: imposing a grid having a plurality of grid cells on the image, each grid cell including a respective subimage; extracting image features from each of the plurality of grid cells; classifying the subimages in each grid cell without using geometric information about the image using a trained classification routine; generating classified image segments from the classified subimages; and generating a class map from the classified image segments. Selected features in the generated class map may then be compared with a database of existing images to determine a potential match. The image may be an iris image, a facial image, a fingerprint image, a medical image, a satellite image
