摘　　要：针对镜头探测过程中出现的一些实际问题,提出了自适应镜头探测模型的思想,并对自适应的概念进行了详细的说明,对视频格式自适应、探测算法自适应以及阈值自适应等3类自适应的可能解决方案进行了初步的探讨。随后给出了设计的镜头探测算法评价模型,并通过4种镜头探测方法的实验对该评价模型进行了验证,结果证明该评价模型能够较为全面地反映镜头探测算法的实际性能。According to some problems of shot detection, this paper proposes a new idea called self-adaptive shot detection model, and then explains the concept of self-adaptive in detail, brings forward some probable solutions of format-adaptive, algorithm-adaptive and threshold-adaptive. Subsequently it designs an evaluation model of shot detection algorithm, which is validated by four shot detection algorithms, and the experiment results prove that the proposed evaluation model is effective.
