Video interpolation algorithm and its VLSI architecture implementation

A video interpolation algorithm based on triangulation analysis and high-frequency compensation is proposed. And its VLSI architecture implementation is given in this. Triangulation analysis can detect and preserve the edges in video frames. Furthermore, high-frequency compensation can improve the fidelity of the frames. The VLSI architecture is regular, and video signal processing speed is very high, because of the regularity of the proposed algorithm. This algorithm and its VLSI implementation have practical value. The experiment results show that this algorithm can obtain the better video frame than conventional interpolation methods. 0.18 μm CMOS technology is employed to implement this algorithm, which consumes about 18.96 mW at 100 MHz work frequency and 1.98 V voltage supply.
