| Abstract: | A new wavelet transform was proposed,which was the differential Haar-Gaussian wavelet transform.This new wavelet transform was applied to the edge detection,which was processed in both spatial and the frequency domains.The bandwidth-matching algorithm and the telecentric optics were used to achieve fast calculation,and to produce high-precision edge detection results with large depth of focus. |
