Automatic region of interest detection based on the motion of the video frame

摘要

The present disclosure is directed to techniques for ROI video processing based on (ROI) detection automatic low-complexity regions of interest within a video frame of the video sequence. Low-complexity automatic ROI detection may be based on the characteristics of the video sensor of the video communications within the device. In other cases, low complexity automatic ROI detection may be based on the motion information about the video frames of the video sequence to another and is a video frame. The disclosed technique, the video sensor calibration of the video communication device, camera processing, ROI detection, to increase and that and adjust the ROI video processing based on the characteristics of the video sensors in particular, including the possible video processing technology . The disclosed technique, moreover, includes an ROI detection techniques based on the sensor, which uses the side information of the camera and processed video sensor statistics in order to improve the detection accuracy ROI. The disclosed technique, as well, and a ROI detection techniques based on the motion, which uses the motion information obtained during the motion estimation during video processing.
