Method and apparatus for objective video quality assessment based on continuous estimates of packet loss visibility
Abstract:
A method for assessing the quality of a transmitted video signal sequence at a receiver side includes: capturing the input video bit stream; extracting at least one feature or a set of features; determining the continuous probability of visibility for each packet loss event which occurred within a specific time interval; and employing the continuous probability of packet loss visibility as a weighting factor of the at least one feature or set of features extracted from the video bit stream to calculate an estimate of the overall quality, Q, of the transmitted video sequence.
