摘要： 提出一种基于三角分析和高频补偿的视频插值算法及其VLSI实现方法。三角分析能够检测并保护视频图像中的边缘信息；高频补偿技术用来进一步改善插值结果图像的视觉效果。算法的规则性决定了对应的VLSI结构的规则性、紧凑性和视频信号处理的高速度。此算法和它对应的VLSI结构有实用价值。用CMOS工艺实现VLSI结构。仿真实验结果表明，用此算法获得的插值结果图像在主观视觉效果和客观评价指标上优于传统的插值算法。VLSI芯片工作在100MHz频率、1.98V电压下，此结构的功耗为18.96mW。

Abstract: 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. CMOS technology is employed to implement this algorithm, which consumes about 18.96mW at 100MHz work frequency and 1.98V voltage supply.

Key words: Video interpolation, Triangulation analysis, High-frequency compensation, VLSI implementation
