摘 要: | 利用滑动窗口来进行镜头边界检测自适应阈值的计算是一种常用的方法。该文提出一种基于颜色——梯度模值二维直方图的自适应镜头边界检测方法。计算出帧间差值以后,在原有高斯模型滑动窗口内部增加一个滑动窗口计算自适应阈值。实验结果表明,该方法能有效避免滑动窗口方法中因窗口大小参数设置所导致的漏检问题,并且使检测性能得到进一步的提高。

Shot Boundary Detection Based on Color-Module Inner Slide Window |
| |
Abstract: | Slide window is a commonly used method for computing adaptive threshold of shot boundary detection.This paper presented a adaptive shot boundary detection.The algorithm computes discontinuity values based on Color-Gradient Module 2D histogram and gets adaptive threshold by added an Inner Slide Window in the Gaussian-Slide Window.Experimental results show that the method is of high performance,because it can avoid omitted detection which produced by the adjustment of the Gaussian-Slide Window's size. |
