Abstract
A method of de-interlacing interlaced video information including determining functional equations which estimate trajectories of corresponding pixel locations based on statistical information, updating each functional equation with sampled pixel values from the interlaced video information of corresponding pixel locations, and evaluating the functional equations at a time point of a progressive frame and providing corresponding progressive pixel values. A video de-interlace system including a trajectory estimator and a component estimator. The trajectory estimator provides functional equations estimating trajectories of tracked pixel locations based on statistical information. The component estimator receives the functional equations and the interlaced video information and provides progressive pixel values. The component estimator updates each functional equation with sampled pixel values from the interlaced video information, and evaluates the updated functional equations at selected time points to provide progressive frames.
