A target object is found in a target image, by using a computer for determining an orientation field of at least plural pixels of the target image, where the orientation field describes pixels at discrete positions of the target image being analyzed according to an orientation, and location. The orientation field is mapped against an orientation field in model images in a database to compute match values between the orientation field of the target image and orientation field of model images in the database. The match values are thresholded, and those match values that exceed the threshold to are counted to determine a match between the target and the model.
