APPARATUS AND METHOD FOR INTERACTIVE QUALITY IMPROVEMENT IN VIDEO CONFERENCING

摘要

An apparatus and method are provided to allow users of a device for video conferencing operating in a very low bandwidth environment to touch or gesture to an object or region of the image that they would like to see with improved quality. The feedback is then sent to the transmitting end where the selected region is encoded with higher quality parameters while other regions are pre-processed and encoded with fewer bits. Depth information, available through a depth camera or other method, may be used to determine the boundary of the selected object as well as to perform depth-based saliency detection and pre-processing of the image in order to reduce the overall required bandwidth.
