摘　　要：针对单一化视频图像"毛刺"现象和压缩比率低等问题,在VR技术基础上提议出一种视频图像处理效果优化方法。根据六个主要运行模块构建出虚拟现实技术系统,从视频图像数据与颜色间关系判定角度出发,分为二进制图像、伪彩色图像以及灰度图像,通过笛卡尔坐标系计算,确定每个中心点的网格图像并量化处理,采用阈值的极值中值滤波算法,对滤波窗口的图像像素排序计算,得到适用于滤波处理的阈值强化图像效果。仿真结果表明,所提方法具有较高压缩比率,人眼视觉效果更优。For the problems of"burr"and low compression ratio of single video image,this paper presented a method to optimize video image processing effect based on VR technology.Based on six operation modules,the VR system was constructed.From the perspective of the relationship between video image data and color,the image was divided into binary image,pseudo-color image and gray image.Through Cartesian coordinate system,the grid image of each center point was determined and quantified.The extreme median filter algorithm of threshold was used to arrange the image pixels in the filtering window.Finally,the effect of threshold enhancement was obtained,which was suitable for filtering processing.Simulation results show that the proposed method has higher compression ratio and better visual effect.
