摘要
提出基于噪声特征参数估计和能量分析的视频运动变化区域自动检测方法。该方法通过基于块的帧差处理,利用相对噪声服从高斯分布的特性和能量的属性的双重约束来检测运动变化区域。利用Matlab实现了相应算法,实验结果表明该方法具有较强的自适应性和应用性。
This paper provides the automatic video motion region detection method based on the noise parameters estimation and energy analysis. This method based on differenced frame process and utilizes double constraints of relative Gaussian noise and block energy to detect the change region. At last, realized the algorithm by the development environment of Matlab. The analytical and experimental results are also given in this paper.
