我们提出了改进的算法，自动衰落和溶解检测在数字视频分析。我们设计了新的两步算法褪色和溶解检测，并介绍了一种方法，用于消除误报从检测到的候选转换列表。在我们对这些渐变镜头过渡的详细研究中，我们的目标是准确地对过渡类型（淡入、淡出和溶解）进行分类，并精确地定位过渡的边界。这使我们的工作区别于场景变化检测的早期工作，其重点是确定过渡的存在，而不是其精确的时间范围。我们在全面的数据集上与其他两种常用方法评估了我们的算法，并展示了由于我们的增强而提高的性能。
We present improved algorithms for automatic fade and dissolve detection in digital video analysis. We devise new two-step algorithms for fade and dissolve detection and introduce a method for eliminating false positives from a list of detected candidate transitions. In our detailed study of these gradual shot transitions, our objective has been to accurately classify the type of transitions (fade-in, fade-out, and dissolve) and to precisely locate the boundary of the transitions. This distinguishes our work from early work in scene change detection which focuses on identifying the existence of a transition rather than its precise temporal extent. We evaluate our algorithms against two other commonly used methods on a comprehensive data set, and demonstrate the improved performance due to our enhancements.
