Frame rate up-conversion is useful for low frame rate pictures such as movie. In case of conversion, basic motion compensation causes gap at covered area and uncovered area. To avoid the gap, we propose the motion compensation centered at the position of target. Fully motion compensated interpolation is possible in this method. To realize this, error normalizing by block activity is used for mo...

The aim of this paper is to improve the convergence rate of frame algorithm based on Richardson iteration and Chebyshev methods. Based on Richardson iteration method, we first square the existing convergence rate of frame algorithm which in turn the number of iterations would be bisected and increased speed of convergence is achieved. Afterward, by using Chebyshev polynomials, we improve this s...

A double stimulus subjective evaluation was performed to determine preferred frame rates at a fixed bit rate for low bit rate video. Stimuli consisted of eight reference color video sequences of size 352 × 240 pixels. These were compressed at rates of 100, 200 and 300 kbps for low, medium, and high motion sequences, respectively, using three encoders and frame rates of 10, 15 and 30 frames per ...
