A new method for estimation of corner angle
Cheng Lan · 2000
Corner feature has considerable position in the field of computer vision. The angle is one of an important feature of corner that is often used as a threshold to decide whether the corner can be utilized. A new algorithm for estimating of corner angle is proposed. The algorithm convolutes the code chain of edge with different mean square in the neighbor the corner. Therefore the different displace of corner can be obtained and the angle of corner be estimated by using this displace. The algorithm has smaller complexity of computation and can estimate corner angle accurately in proper field. The analyses of computing errors is shown.
