A method for product recognition from multiple images includes producing a plurality of recognition results for a plurality of input images, stitching the plurality of input images into a single stitched image; merging the plurality of recognition results using information from stitching the plurality of input images to generate a merged recognition result; and outputting the merged recognition result. The disclosure also includes systems for implementing the method.

Method for product recognition from multiple images

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.

Real-time smart display detection system

The disclosure includes a system and method for switching between video views and data views. The system includes a controller, a view presentation module, a screen detection module and a view switching module. The controller receives data indicating a participant joined a multi-user communication session. The view presentation module presents a video stream on a mobile device associated with the participant. The screen detection module determines an occurrence of a detection trigger event. The controller receives a video frame image responsive to the occurrence of the detection trigger event. The screen detection module detects a data screen in the video frame image. The view switching module switches a view on the mobile device from video view to data view responsive to a natural gesture performed by the participant. The view presentation module presents a data stream associated with the data screen on the mobile device.
