A Location Method Based on Image Fingerprint Recognition

A principle of image fingerprint identification and location is put forward in accordance with the features of image fingerprint.Firstly,an approach of higher order surface fitting is taken to obtain the image edge detection result.Next the randomized Hough transform method of the grid-search is exploited for the identification of round fingerprint features.Then the image position is got on the basis of prior knowledge of geographic pattern,and the target is finally located.The simulation result shows that an accurate identification and location of image fingerprint can be achieved through this method,which can calculate its position as well as size in the image and makes the image target identification and location feasible and efficient.
