Adaptive corner detection based on slide windows

Boundary-based corner detection algorithm has many shortcomings,such as the error of discretization and poor localization accuracy of corner point.Based on curvature and slide windows,an adaptive corner detection algorithm is proposed.Adaptive slide window strategy is applied to select the optimal support field of boundary point.The new curvature calculation method is presented to transform two-dimension planar curve to one-dimension curve,then the singularities of one-dimension curve means the corner point on planar curve.The simulation results indicate the superiority of our algorithm to these other methods.
