This trend triggers the virtual advertising comes up recent years, especially for sport videos which bring tremendous commercial potentials. The concept of virtual advertising is to bring brand names or other advertising messages into scenes, thus the audience can focus on the game while impressed with advertisement unconsciously. However, the task is labor intensive and inefficient by manually. In this thesis, a novel approach to build up a more comprehensive scheme which will equilibrate on promoting cognitive effectiveness but curtailing visual intrusiveness for tennis highlight videos is proposed. This approach determines appropriate insertion timing according to the structure of video sequence and the visual features gathered in each frame. The inappropriate locations are masked using the proposed attention analyzing procedure through spatial and temporal examination. In order to promote advertising effectiveness, two considerations of significant localization also take into account in the implementation. Then, an advertising selection mechanism with color relevance is implemented to reduce visual interference from the perspective of user experiences. The objective assessments demonstrate that this advertising insertion approach is both effective and adequate. In addition, the subjective evaluation results show that the insertion method with predefined criteria is accordant to user study experiments.
