Which edge detection method is best?
The Canny Edge Detection algorithm is a widely used edge detection algorithm in today's image processing applications.
Which of the following approach is used for the edge detection?
Laplacian of Gaussian
In an image, Laplacian is the highlighted region in which rapid intensity changes and it is also used for edge detection. The Laplacian is applied to an image which is been smoothed using a Gaussian smoothing filter to reduce the sensitivity of noise.
Which technique is applied for edge segmentation?
The Sobel technique of edge detection for image segmentation finds edges using Sobel approximation derivative [6]. It performs a 2-D spatial gradient measurement on an image and so emphasizes regions of high spatial gradient that corresponds to edges.
