Patent ID: 8160385

Claim:
A method comprising: accessing component images of a target image; analyzing the accessed component images; based on the analysis of the accessed component images, identifying, in a first component image of the target image, a partially detected blotch that is not included in at least one other of the accessed component images; and refining the partially detected blotch by: determining a first metric for the partially detected blotch included in the first component image; identifying a region of the first component image that touches the partially detected blotch included in the first component image; determining a second metric for the identified region; comparing the first metric for the partially detected blotch with the second metric for the identified region to produce a result that indicates how similar the identified region is to the partially detected blotch; and adding the identified region to the partially detected blotch based on the result indicating that the identified region is similar to the partially detected blotch.
