Abstract: Methods and systems for gesture-based control of a device are described. An input frame is processed to determine a location of a distinguishing anatomical feature in the input frame. A virtual gesture-space is defined based on the location of the distinguishing anatomical feature, the virtual gesture-space being a defined space for detecting a gesture input. The input frame is processed in only the virtual gesture-space, to detect and track a hand. Using information generated from detecting and tracking the at least one hand, a gesture class is determined for the at least one hand. The device may be a smart television, a smart phone, a tablet, etc.

Abstract: This application discloses an obstacle detection method, including: obtaining a first image, where the first image is an image encoded based on an RGB model; reconstructing the first image to obtain a second image, where the second image is a hyper spectral image; and extracting a hyper spectral feature from the hyper spectral image, and classifying a candidate object in the hyper spectral image based on the hyper spectral feature to obtain an obstacle detection result. Because different textures correspond to different hyper spectral features, classifying candidate objects in hyper spectral images based on the hyper spectral features can distinguish an object that has a similar color but a different texture.
