The concentration factor edge detection method was therefore developed to realize an edge detector directly from spectral data this thesis explores the possibilities of detecting edges from the phase of the spectral data, that is, without the magnitude of the sampled spectral data. The canny edge detector is widely considered to be the standard edge detection algorithm in the industry it was first created by john canny for his master’s thesis at mit in 1983 , and still outperforms many of the newer. Edge detection includes a variety of mathematical methods that aim at identifying points in a digital image at which the image brightness changes sharply or, more formally, has discontinuities the points at which image brightness changes sharply are typically organized into a set of curved line segments termed edges.
