Design of steerable filters for feature detection using canny-like criteria
We propose a general approach for the design of 2D feature detectors from a class of
steerable functions based on the optimization of a Canny-like criterion. In contrast with …

The canny edge detector revisited
W McIlhagga - International Journal of Computer Vision, 2011 - Springer
Abstract Canny (IEEE Trans. Pattern Anal. Image Proc. 8 (6): 679-698, 1986) suggested that
an optimal edge detector should maximize both signal-to-noise ratio and localization, and …

Edge detection by scale multiplication in wavelet domain
L Zhang, P Bao - Pattern Recognition Letters, 2002 - Elsevier
This paper proposes a wavelet based edge detection scheme by scale multiplication. The
dyadic wavelet transforms at two adjacent scales are multiplied as a product function to …
