Abstract
A system and method for object recognition is presented. The system is based on finding invariant common features in source and target images, projecting these features into a four dimensional space comprised of the x,y coordinates of each feature on source and target image, and detecting the existence (or lack thereof) of a sufficient number of such points on a single hyperplane or hypersurface. The existence of such a hyperplane or surface indicates a match between source and target.
Claims2
A method for determination of similarity between a first image and a second image pairs consisting of the steps:
- a. determining a set of features on each image;
- b. determining matching features from said sets that are common to both images;
- c. plotting each such matching feature pair as a 4-dimensional point comprising the x,y coordinates of said features in said first image and the x,y coordinates of said features in said second image;
- d. determining the smoothness of a surface fitting said 4-D points;
- e. determining a measure of correspondence depending upon said smoothness and the number of said matching features
- whereby a measure of image correspondence is determined even for images that have undergone nonlinear transformations.
