摘　　要：多帧视频图像视觉传达方法存在图像噪声高、图像质量不佳等问题,提出基于光谱成像的多帧视频图像视觉传达方法。通过图像梯度向量获取视频图像,根据视频图像中边缘模糊程度估算图像的深度值,在红、绿、蓝颜色空间上对图像展开编码,构建阶跃边缘函数实现多帧视频图像颜色补偿,通过八叉树对多帧视频图像色彩进行量化,提取图像主色彩特征,根据光谱成像技术确定视频图像关键帧,实现多帧视频图像视觉传达。实验结果表明,所提方法图像质量高,时间消耗仅为3秒,多帧视频图像视觉传达效果好。Multi-frame video image visual communication methods have some problems,such as high image noise and poor image quality.This paper proposes a multi-frame video image visual communication method based on spec-tral imaging.Gradient vector for video image from the image,according to the video image estimate the depth value of image edge blur degree,in red,green,and blue color space of image coding,build step edge function more video im-ages color compensation,by octree to quantify the video images more color,extract the image main colour characteris-tics,The key frame of video image is determined according to spectral imaging technology,and multi-frame video im-age visual communication is realized.The experimental results show that the proposed method has high image quality,the time consumption is only 3 seconds,and the visual communication effect of multi-frame video images is good.
