A critical component of any video transmission system is an objective metric for evaluating the quality of the video signal as it is seen by the end-user. In packet-based communication systems, such as a wireless channel or the Internet, the quality of the received signal is affected by both signal compression and packet losses. Due to the probabilistic nature of the channel, the distortion in ...

INTRODUCTION While most of us have a general idea of distortion and know that it deteriorates the signal, it may be useful to re-state what is distortion. When a signal is processed through an electronic circuit, the output of the circuit often contains unwanted signals which were not part of the input. These unwanted output signal's frequency is usually related to the input signal's frequency....
