Feature points extraction is a common computer vision task where Harris Corner Detector fits well. Corners are important features of an image, since they provide useful information for objects detection. […]Read: "Feature Points Extraction using Harris Corner Detector"
The gradient Non-maximum suppression also known as edge thinning is a process of extracting thin, one pixel wide object’s contours. This process follows gradient detection as a post processing step. […]Read: "Gradient Non-Maximum Suppression"
The Sobel filter (also called Sobel-Feldman operator) is an edge detection filter, that results in image emphasizing edges. Computer vision and image processing applications frequently use this filter to extract image […]Read: "Sobel Filter – Sobel-Feldman Edge Detection and Gradient Extraction"
The Median filter is a nonlinear noise reduction filter that is widely used in image processing. It is very effective in cases of salt and paper noise (impulsive noise) and […]Read: "Median Filter – Edge Preserving Filter"
The Hough Transform is a method to find shapes in an image. The classical transformation is initially designed to identify lines in the image. Later the transform extends to identify […]Read: "Hough Transform – Basic Shape Detection"
