Video super-resolution is the process of estimating a high resolution image from a motion sequence of low-resolution image frames. This paper examines the convergence prop erties of the modified Kalman filter super-resolution algo rithm introduced in [1]. Most significantly, the ratio of the system and measurement noise variances is shown to be a highly useful control parameter of the convergence rate, super-resolution image sharpness, and the algorithm's be haviour in the presence of noise.
