This article,the method of weighting histogram-neglecting intersected block maximum value is proposed,and it s used to propose an improved window law to detect abrupt change,and a improved non-neighbor frame difference based method to detect gradual change with existing algorithms.
提出了忽略分块极大值的加权直方图的方法,并结合此概念及现有算法分别提出一种改进的窗口法来检测突变和一种改进的基于非相邻帧差法来检测渐变,更加精确地实现了镜头的分割以及对镜头边界点的定位。
补充资料:算术平均值滤波
分子式:
CAS号:
性质:数字滤波最简单和最常用的一种,方法是在某时刻对信号进行连续多次多样,对采样值进行算术平均,作为该时刻的信号值,连续采样的次数视具体情况而定。算术平均值滤波对抑制周期性干扰和随机干扰有良好效果。
