ABSTRACT:
A system for inserting images into live video fields includes a method for rapidly and efficiently identifying landmarks and objects. Initially a first template, having a first pattern similar to one of the distinctive features of the object, is passed over the video field and compared to it in order to preliminarily identify at least one possible distinctive feature as a candidate. A second template is then created by taking one of the major elements of the distinctive feature candidate and extending that element all the way across the second template and then comparing it to the distinctive feature candidate. This eliminates one or more possible falsely identified features. A third template is then created having a pattern formed from another major element of said distinctive feature and extending it all the way across the third template. The third template is then likewise passed over the distinctive feature candidate and compared therewith in order to eliminate still further falsely identified features. The method is continued until all possible false alarm candidates have been eliminated. The process is then repeated in order to preliminarily identify two or three landmarks of the target object. The locations of those objects are then compared to a geometric model to further verify if the object has been correctly identified. The methodology can be tested against a video taped program to determine if it accurately identifies objects.
