Create a computer vision system using decision tree algorithms to solve a real-world problem : Feature Extraction - SIFT

The video tutorial introduces feature detectors commonly used in face recognition, focusing on the FAST algorithm. It explains the concept of corner detection, comparing it to the Harris corner detection method. The tutorial details how the FAST algorithm works by selecting a pixel, determining its intensity, and using a threshold to identify corners. It also discusses practical considerations, such as the availability of certain algorithms in OpenCV due to patent restrictions, and highlights the non-patented status of the FAST algorithm, making it freely usable.
