How the edges are detected from image?
Edge detection is an image processing technique for finding the boundaries of objects within images. It works by detecting discontinuities in brightness. Edge detection is used for image segmentation and data extraction in areas such as image processing, computer vision, and machine vision.
How can EDGE be detected?
The search-based methods detect edges by first computing a measure of edge strength, usually a first-order derivative expression such as the gradient magnitude, and then searching for local directional maxima of the gradient magnitude using a computed estimate of the local orientation of the edge, usually the gradient ...
What is the best edge detection method?
Canny Operator
Canny edge detector is probably the most commonly used and most effective method, it can have it's own tutorial, because it's much more complex edge detecting method then the ones described above.
