Abstract:
1. A method of creating image mosaics, comprising: analyzing input images, revealing matching points, the matching points being special points, and determining descriptors for the respective matching points; performing pair-wise comparison of the input images by matching of the special points; choosing a reference image from the input images; choosing remaining input images after choosing the reference image one-by-one in a predetermined order, the predetermined order being determined by computing a quantity of matching descriptors of each of the remaining input images with descriptors of the reference image and analyzing the computed quantity of matching descriptors of each of the remaining input images with descriptors of the reference image, and recovering parameters of rotation/translation of each of the remaining input images relatively to the reference image, after the reference image is compared by points and descriptors of the remaining input images; and compositing the remaining input images one-by-one with the reference image in the predetermined order, using the recovered rotation/translation parameters so that a seam between the composited remaining input images and the reference image is visible as little as possible, wherein in the course of pair-wise matching of special points a square-symmetric table is formed consisting of quantity of compatible points for each pair of images.
