How do we detect edges?

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 does Matlab detect falling edges?

Transition out of state if the value of the input data signal falls below a threshold of 2.5. The falling edge is detected when the value of the expression signal-2.5 becomes zero or negative.

Which one filter is used for finding edges?

The Canny filter is a multi-stage edge detector. It uses a filter based on the derivative of a Gaussian in order to compute the intensity of the gradients. The Gaussian reduces the effect of noise present in the image.
