Claim 8:
9. A computer-implemented method for evaluating similar content-based images, the method comprising:
receiving a first image, wherein the first image includes at least one first object;
receiving a second image, wherein the second image includes at least one second object;
computing a structural similarity index measure (SSIM) value based on the at least one first object and the at least one second object;
computing a scale invariant feature transform (SIFT) value based on the at least one first object and the at least one second object;
computing an adjusted SIFT value by multiplying the SIFT value by an SSIM factor;
computing a histogram value based on the at least one first object and the at least one second object;
computing an adjusted histogram value by multiplying the histogram value by an SSIM factor and by a SIFT factor;
computing a sum of the SSIM value, the adjusted SIFT value, and the adjusted histogram value; and
computing a similarity score based on the sum of the SSIM value, the adjusted SIFT value, and the adjusted histogram value.
