Abstract: A template matching algorithm based on contour-feature is presented.Key-frames are extracted from the video and sent to a template store,then deals the templates with image pre-processing and feature extraction.The similarity matching is carried out by Contour-based Similar Distance(CSD) function with the binary images.The experiment of intelligent advertisement detecting system shows that the algorithm is simple and meets the requirements on matching velocity and rate.

Key words: image pre-processing, contour-feature, template matching, intelligent advertisement detecting system

摘要: 提出一种基于轮廓特征的模板匹配方法,该方法首先提取视频关键帧作为模板库,然后对模板库中的图像进行图像预处理和特征提取,利用基于轮廓特征的相似距离函数(CSD)对处理后的二值图像进行相似性匹配。智能广告监播系统应用实验表明该方法不仅简单,而且能满足匹配速率和匹配率上的需求。
