基于偏微分的图像放大算法在视频监控中的应用

摘要

The video surveillance system is an important part of the securitysystem,it is an strong integrated system to guard against the security problem.Video surveillance with its intuitive,accurate,timely and rich information content and is widely used in many occasionsfor getting a better visual effect and video surveillance screen playback for special occasions.Demandingan effective magnification algorithm is presented to enlarge the image.Relative to the shortcomings of traditional amplification algorithm which is difficult to obtain high-resolution quality image,magnification algorithm based on partial differential can better keep the edges of the image features and details,so as to get high-resolution quality image.%视频监控是安全防范系统的重要组成部分,它是一种防范能力较强的综合系统。视频监控以其直观、准确、及时和信息内容丰富而广泛应用于许多场合。针对视频监控中画面回放的特殊场合和获得较好的视觉效果的需求,相对于传统放大算法难以获得高分辨率的优质图像的缺点,基于偏微分的图像放大算法,能较好地保持图像的边缘特征和细节信息,从而获得清晰的放大图像。
