Method for Identifying Pairs of Derivative and Original Images
First Claim
1. A computer-implemented method of detecting one or more archive images matching a search image, each matching archive image being a derivative of the search image or being an original image the search image was derived from, the method comprising:
- accessing a plurality of the archive images;
for each of said archive images, computing a respective archive image histogram, each archive image histogram comprising a plurality of combination micro-feature values, and storing said archive image histogram to a database;
receiving a search image;
computing a search image histogram from said search image, the search image histogram comprising a set of combination micro-feature values;
comparing the combination micro-feature values of the search image histogram with the combination micro-feature values of the archive image histograms to identify one or more candidate archive image histograms; and
respectively comparing the one or more candidate archive image histograms with the search image histogram to identify one or more matching archive images as being a derivative of the search image or as being the original image the search image was derived from.

Abstract
The invention provides for a computer-implemented method for detecting one or more archive images matching a search image, each matching archive image being a derivative of the search image or being an original image the search image was derived from accessing a plurality of the archive images. For each of said archive images, a respective archive image histogram may be calculated, wherein each archive image histogram includes a plurality of combination micro-feature values. The archive image histogram may be stored to a database.
