Hough Transform for Line and Shape Detection - Lecture 18

Explore the Hough Transform technique in computer vision through this 48-minute lecture by Dr. Mubarak Shah from the University of Central Florida. Delve into image feature extraction, shape features, and various line-fitting methods including Least Squares Fit and RANSAC. Learn the Hough Transform algorithm for fitting straight lines, understand image gradients, and see practical examples of line and circle fitting. Discover the Generalized Hough Transform, R-table generation, shape detection, and methods for achieving rotation and scale invariance in object recognition.
