WebJun 8, 2024 · Let us see these steps in more detail. 1. Noise Reduction. Edge detection is sensitive towards image with noise. If the noise is not removed from the image then the edge detection results will not be good. So the first step is the preprocessing of the image to eliminate noise. This can be done by applying Gaussian filters.
