Techniques for objectively measuring motion distortion in video teleconferencing systems

A description is presented of three different techniques for measuring motion distortion in video teleconferencing and videophone (VTC/VP) systems: temporal frequency response, scene cut response, and transmitted frame rate. All three techniques satisfy the two basic requisites for a measurement procedure to be practical. First, the measurements are performed using only the output processed picture. Second, the techniques for generating the test signal and analyzing the output signal are not excessively complex so there is promise of developing practical test equipment to implement the test procedure.<
