With has been corrected by the energy analysis . other way is the motion-changed region detection algorithm based on fuzzy entropy clustering in time-differenced image 第二种方法是基于时差分模糊熵聚类的运动变化区域检测算法。
This method based on differenced frame process and utilizes double constraints of relative gaussian noise and block energy to detect the change region 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。
By means of analyzing the designing parameters of less tooth differenced planetary transmission mechanism with biasing crankshaft, it is pointed out that the meshing angle is a key factor which affects the transmission function of the mechanism 摘要通过对偏曲轴少齿差行星传动机构设计参数的分析,指出啮合角是影响机构传动性能的一个关键因素。
Owing to the fact that the wavelet transformation possesses localization and implicit difference property, the suthors show that after wavelet tansformation, the fractionally differenced process and the harmonizable periodically correlated process may be changed into stationary processes 利用小波的局部性及暗含的差分性质,证明了在小波变换后,分数差分平稳过程和可调和周期相关过程是平稳的。
First, we analysis the general theoretical model of video segmentation . secondly, based on the model, an automatic detection algorithm of motion-changed regions is proposed from the point of fuzzy entropy clustering . motion-changed regions are detected, using a fuzzy clustering rule to distinguish between the relative noisy and motion-changed regions in time-differenced image 论文首先讨论了时差分视频分割的一般理论模型,然后在建立的视频分割模型的基础上,从模糊熵聚类的角度出发提出了一种视频运动变化区域自动检测的方法,通过建立的模糊分类准则在差分图像中对运动变化区域和相对噪声区域进行划分,从而得到运动变化区域。
