摘要
视频分割技术常用于大显示屏的场合,分割技术的好坏决定着视频显示的清晰程度。采用三次拉格朗日插值算法,以改善视频分割处理时图片失真问题,提出改进算法,即重心拉格朗日插值法,用硬件描述语言VHDL来实现算法并进行软件仿真。
Video segmentation techniques are commonly applied in a large screen where segmentation technique determines clarity of the video display. Interpolation algorithm is used to improve the video image distortion by using cubic Lagrange interpolation algorithm. The improved algorithm of Barycentric Lagrange Interpolation is studied. And the VHDL hardware description language is used to implement algorithms and software simulation.
