Comments on "Techniques for edge detection"

Automated Detection of the Arterial Inner Walls of the Common Carotid Artery Based on Dynamic B-Mode Signals

“…The design of f x for the IMT and LD detection is different. The MacLeod filter is defined as follows [18]: $f_{M}false(x,\hspace{0.17em}yfalse)=\text{exp}false(-\frac{x^2+y^2}{d_c^2}false)false[\text{exp}false(-{false(\frac{d_{xy}+d_{pk}}{d_{pk}}false)}^{2}false)-\text{exp}false(-{false(\frac{d_{xy}-d_{pk}}{d_{pk}}false)}^{2}false)false]$where: d c constant; determining the rate of radial decay, d pk distance from axis to peaks in positive and negative weights, d xy = x sin θ – y cos θ , perpendicular, distance of point ( x,y ) from axis of edge (at orientation θ to horizontal).…”

Convolution-Based Edge Detection for Image/Video in Block DCT Domain

“…This block-DCT ment, a large size mask is required [21,22]. This is espe-scenario also serves as a core in many video compression cially true for halftone images with fine microstructure.…”

Edge detection using neural network arbitration

“…Macleoad [104] presents a different function, consisting of the difference of two inverted exponential functions weighted by a third exponential. Abdou [1], uses a lOx10 mask to reduce computational complexity of the above formulae.…”
