摘要
电视广告的曝光频率对广告的定价非常重要。如果我们按人来计算这种曝光频率,将会非常耗时且容易出错。本文提出了一种搜索和统计体育视频中出现的横幅广告数量的方法,并设计了一个系统。使用颜色直方图和SURF (accelerated - up Robust Features)算法匹配预先指定的样本广告中的特征点,从而进行搜索。该搜索方法可以鲁棒地识别缩放和部分遮挡中的目标,同时达到接近实时的性能。这个系统在我们使用真实视频的实验中有效地工作了。
A banner ads searching and counting system for sports videos
The ads exposure frequency in a TV is very important for the pricing of the advertising. If we count this exposure frequency by person, it will be very time consuming and error-prone. In this paper, we propose an approach and design a system for searching and counting the number of banner ads appearing in sports videos. The searching proceeds by matching feature points from pre-specified sample ads using the color histogram and the SURF (Speeded-Up Robust Features) algorithm. This searching approach can robustly identify objects among scaling and partial occlusion while achieving near real-time performance. This system worked effectively in our experiments using real videos.
