  • System and method for identifying image locations showing the same person in different images
    Patent number: 9275299
    Abstract: The same person is automatically recognized in different images from his or her clothing. Color pixel values of a first and second image are captures and areas are selected for a determination whether they show the same person. First histograms of pixels area are computed, representing sums of contributions from pixels with color values in histogram bins. Each histogram bin corresponds to a combination of a range of color values and a range of heights in the areas. The ranges of color values are normalized relative to a distribution of color pixel values in areas. Furthermore, second histograms of pixels in the areas are computed, the second histograms representing sums of contributions from pixels with color values in further histogram bins. The further histogram bins are at least partly unnormalized. First and second histogram intersection scores of the first and second histograms are computed. A combined detection score is computed from the first and second histogram scores.
