CenSurE (Center Surround Extremas) is an algorithm that detects keypoints by finding extrema of center-surround filter responses. Using box-shaped filters and integral images, it computes faster than SIFT and SURF while finding extrema at the original resolution at every scale. In OpenCV it is implemented under the name STAR detector.
