Corner extraction is an important task in many computer vision systems. The quality of the corners and the efficiency of the detection method are two very important aspects that can greatly impact the accuracy, robustness and real-time performance of the corresponding corner-based vision system. In this paper we introduce a fast corner detector based on local binary-image regions. We verify the performance of the proposed method by measuring the repeatability rate under various illumination, scale and motion conditions. Our experimental results show that while the quality of the features is comparable with other conventional methods, ours delivers a faster performance.
