Hough edge detection
WebMar 2, 2024 · Apply canny Edge Detector (adjust the thresholds — trial and error) to get edges. Define Region of Interest. This helps in weeding out unwanted edges detected by canny edge detector. Retrieve Hough lines. Consolidate and extrapolate the Hough lines and draw them on original image. Original Test Images In automated analysis of digital images, a subproblem often arises of detecting simple shapes, such as straight lines, circles or ellipses. In many cases an edge detector can be used as a pre-processing stage to obtain image points or image pixels that are on the desired curve in the image space. Due to imperfections in either the image data or the edge detector, however, there may be missing points or pixels on the desired curves as well as spatial deviations between the ideal lin…
