WebIt was developed by John F. Canny in 1986. It is a multi-stage algorithm that provides good and reliable detection. So, let’s discuss the main steps used in the Canny Edge detection algorithm using OpenCV-Python. 1. Noise Reduction. An edge detector is a high pass filter that enhances the high-frequency component and suppresses the low ones. WebOct 12, 2024 · Of the available algorithms in Matlab (Sobel, Canny, Prewitt, and Roberts), Canny performed the best in detecting shape outlines (Figure 6a). Canny uses two thresholds which makes it less likely to be fooled by noise and more likely to detect true weak edges. The values for the high and low thresholds are 0.1 and 0.04, respectively.
