Abstract
A method and system of communicating visual communication quality information, includes extracting reduced-reference (RR) feature data from visual content, embedding the RR feature data in the visual content; and transmitting the visual content with the embedded RR feature data. Visual communication quality is assessed by receiving visual content which includes visual content data and a first set of embedded RR feature data, retrieving the first set of RR feature data from the visual content data, and generating a second set of RR feature data from the visual content data. The second set of RR feature data corresponds to substantially identical features of the visual content data as that used to generate the first set of RR feature data. The first set of RR feature data is compared to the second first set of RR feature data to determine a quality of the visual content based upon the comparison.
