Colorblind accessible image search
First Claim
1. 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.

Abstract
Colorblind accessible image search technique embodiments are presented that re-rank the results of a relevance-ranked image search to account for the accessibility of the images to a colorblind person. This is accomplished by first computing a colorblind accessibility quantity for each image of interest in the search results. A colorblind accessibility quantity quantizes the degree to which color information is preserved when an image is perceived by a colorblind person viewing the image. It is computed by generating a colorblind version of an image that simulates how the image would appear to the colorblind person. An amount quantifying the loss of color information between the image and the colorblind version of the image is then estimated. This estimate is used to compute the colorblind accessibility quantity for the image. Once the colorblind accessibility quantities have been computed, the image search results are re-ranked based on these quantities.

11. A system for re-ranking the results of a relevance-ranked image search to account for the accessibility of the images to a colorblind user, comprising:
-
a general purpose computing device; one or more image databases which are in communication with the computing device; and a computer program comprising program modules executable by the computing device, wherein the computing device is directed by the program modules of the computer program to, input a designation of the type of colorblindness the user suffers from, input results of a relevance-ranked image search, generate colorblind versions of images discovered in the search, said colorblind versions simulating how the associated images would appear to a person suffering from the designated the type of colorblindness, compute a colorblind accessibility quantity for each images 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, re-rank the images of interest in the search results based on a combination of the relevance rankings and rankings derived from the colorblind accessibility quantities, and provide the re-ranked results to the user.
