Abstract

We propose a new differential Haar–Gaussian (DHG) wavelet transform together with the bandwidth matching algorithm to perform edge detection, which can be processed with fast computation in both spatial and frequency domains. The telecentric optics is used to produce high-precision edge detection with large depth of focus.
