Computer Vision

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.


Object Detection

FindFaces find human faces in an image

RemoveBackground detect background from foreground and remove it

Object Recognition

ImageInstanceQ test whether an image shows a particular object

TextRecognize extract characters from an image

BarcodeRecognize extract the barcode from an image
