Explore the concept of Bag-of-Features (Bag-of-Words) in computer vision through this 47-minute lecture from the University of Central Florida's 2012 Computer Vision course. Delve into image classification techniques, feature distribution, texture elements, and the use of visual words. Learn about dense features, clustering methods like K-means algorithm, and classification approaches including support vector machines. Understand the importance of linear and nonlinear boundaries in image recognition, and gain insights into the Pascal Competition and evaluation matrices. Presented by Dr. Mubarak Shah, this lecture provides a comprehensive overview of Bag-of-Features methodology and its applications in computer vision.
