Computer Vision
Topic Overview Using a variety of state-of-the-art methods, the Wolfram Language provides immediate functions for image identification and object detection and recognition, as well as feature extraction. The Wolfram Language supports specific geometrical features such as edges and corners, as well as general keypoints that can be used to register and compare images.
