Patent ID: 8412694

Claim:
A computer-implemented process for re-ranking the results of a relevance-ranked image search to account for the accessibility of the images to a colorblind person, comprising using a computer to perform the following process actions: inputting a designation of the type of colorblindness the colorblind person suffers from; obtaining results of a relevance-ranked image search; generating colorblind versions of images discovered in the search, said colorblind versions simulating how the associated images would appear to a person suffering from said type of colorblindness the colorblind person suffers from; computing a colorblind accessibility quantity for each image of interest in the search results based on the associated colorblind versions of the images, said colorblind accessibility quantity quantifying the degree to which color information is preserved when an image is perceived by a colorblind person viewing the image; and re-ranking the images of interest in the search results based at least in part on the computed colorblind accessibility quantities.
