Nomenclature Walrus Vision Toolbox

3.1 Marr-Hildreth operator. The valley region in Loess Plateau is of obvious morphological characteristics. They are composed of loess interfluves, gully-slope lands and valley bottom lands. Among them, loess shoulder-lines are the dividing lines between smooth loess interfluves and steep gully-slope lands.

CHAPTER 4 EDGE DETECTION TECHNIQUE Shodhganga

The Marr-Hildreth edge operator, which is sometimes called the 2G or difference-of-Gaussians (DOG) operator, can be implemented in many different ways. A comparison of several methods shows that

Comparison of Edge Detection Techniques Applied in the

The Marr–Hildreth operator is in fact a combination of these two filter types — a band pass filter — which first preprocesses the image by smoothening it and then detects the edges. Marr and Hildreth suggest a Gaussian blur function G σ as a smoothener, where G σ is defined as

Marr and Hildreth [26] have proposed that edges are detected in the human visual system by an operator that approximates A(7, where A is the Laplacian and G is a rotationally symmetric Gaussian.

In fact, a one-di-mensional Marr-Hildreth edge detector is almost identi-cal with the operator we have derived because maxima in the output of a first derivative operator will correspond to zero-crossings in the Laplacian operator as used by Marr and Hildreth.
