摘要：
The process of key frames extraction is facing human subjectivity. The objectives of key frames extraction are mainly two objectives. The first objective is minimizing the number of extracted key frames. The second objective is maximizing the visual representation of a video shot that the key frames should have. There is a tradeoff between the two objectives. Also the needs of individuals are varied. Some individuals favor the compression ratio and others favor the representation level. Many works depend on a subjective ground truth of the key frames for assessing the performance of key frames extraction methods. In this paper we propose a key frame extraction system that takes a confidence level as input from the user to satisfy the different needs. We evaluate our system using fair measures which are the compression ratio and the fidelity that are directly related to the confidence level.
