Patent attributes
A smart display detection system is disclosed. The smart display system is configured to allow mobile users to connect with display screens through mobile device cameras. The system can detect the display screens within images captured by the mobile device camera in real time by matching the camera query image with screen images dynamically updated from the display devices. A synchronized time-stamped matching strategy is applied to achieve high performance in detecting the screens playing motion intensive video contents and an aggressive feature selection method is applied to minimize the system uploading bandwidth. The system can accurately find display screens playing either static or dynamic content within an image captured on a mobile device.
