bounding edge of pianar object. A method of detecting and iocaiizing corners of pianar curvature based on Gaussian

scaie space is presented. An adaptive curvature estimate method measures the significance of each point on

the boundary preprocessed by Gaussian smoothing；then a criterion is estabiished to choose the desired corner

points. The method reguires no input parameter，and experiments were performed to show that the scaie space

corner detector based on Gaussian smoothing is reiiabie for objects with muitipie-size features and noisy boundaries.

Key words Gaussian smoothing；scaie space；adaptive；corner detection
