An apparatus and method to find a specified number of corners and/or interest points in an image is presented. In some embodiments, a method to find a specified number of corners in a digital image comprises receiving a digital image containing a plurality of candidate corners; directly calculating a threshold score (S) for a center pixel, for each of the plurality of candidate corners, to form a plurality of scores; sorting, by the plurality of scores, the plurality of candidate corners to form a sorted list; and selecting corner locations sequentially from the sorted list based on the certain number of corners. The methods described may be implemented using any combination of hardware, software and firmware.
