Abstract

The method of image relevance determination by comparing of description fragments is discussed in its entirety. Firstly, it is required to detect key points of the image and compute their detectors. Then detectors presented as binary vectors need to be split into fragments. After that, we need to count frequencies of all values that fragments can evaluate to. Lastly, as we got a frequency set for each fragment of two images, we may calculate a numeric image distance by using element-by-element absolute difference. An example of such calculation for two similar images is provided below.
