Abstract:
1. A system for evaluating video quality of a transmitted video sequence, comprising: a transmitter configured to generate feature parameters from an inputted reference video sequence and transmit the feature parameters and encoded video data via a network, wherein the transmitter comprises: a video input unit for inputting a reference video sequence; an edge detection unit for extracting edge pixels from the reference video sequence inputted to the image input unit; an edge video generation unit for generating an edge video sequence from an output of the edge detection unit, wherein the pixels in edge areas of the edge video sequence have an original pixel value of the reference video sequence; an encoding unit for encoding the reference video sequence and generate an encoded video data; an edge video encoding unit for encoding the edge video sequence to include feature parameters comprising information on the original edge pixel values along with their location information; and a communication unit configured to transmit the encoded video data separate from the encoded edge video data to a network and to receive a video evaluation report result from the network.
