DirectShow框架下对比度分辨率补偿的视频挖掘

摘要

在DirectShow平台下,建立一个对比度分辨率补偿的变换Filter,实现低照度视频的底层挖掘.通过本地视频文件的挖掘实验,取得了良好的视觉效果,验证了对比度分辨率补偿算法用于低照度视频的底层图像挖掘的可行性与有效性.%On DirectShow platform,a transformation filter is constructed to realize lower layer video mining which is taken under lower luminance (low night level) condition. Through mining experiments with the obtained video files, nice visual results are achieved. It confirms the feasibility and validity of the contrast resolution algorithms that is used to mine lower layer video taken under lower luminance condition.
