A Novel Shi-Tomasi Corner Detection Algorithm Based on Progressive Probabilistic Hough Transform

The Hough transform is introduced into the image processing field to solve Line detection, curve detection Edge extraction and other problems. A novel Shi-Tomasi corner detection algorithm based on Progressive Probabilistic Hough Transform (PPHT) is proposed to meet the needs of corner detection. In the algorithm, image processing includes filtering, conversion to grayscale and edge detection, then PPHT is used to deal with the images and thus to combine with Shi-Tomasi algorithm for obtaining more accurate detection result. Experiment results in corner detection of images show that the proposed method helps decrease the misdetection and false corner better than the traditional Shi-Tomasi algorithm.
