基于小波变换的亚像素边缘检测

Sub-pixel Edge Detection Based on Wavelet Transform

提出一种基于小波变换的亚像素边缘检测方法,从理论上证明该方法不存在原理误差,同时具有较强的抗噪能力。实验表明,在对光源等无特殊要求的情况下,该方法的精度优于0.02个像素,从而验证了理论的正确性。

A new sub-pixel edge detect.ion method is presented, which is based on the wavelet transform. From the theory it was proved that the operator had no principle error and better anti-noisy ability. The experiments on the location detection showed that the position precision of the operator is better than 0.02 pixel when the system is not requested special lights. Therefore, the accuracy of the theorem is proved.
