Order determination is accomplished in two stages, i.e., the AR order is first determined by the minimum eigenvalue of overdetermined instrumental variable product moment and the MA order is then estimated by the minimum eigenvalues of a covariance matrix derived from the observed data.
该方法将ARMA模型的结构辨识分两步进行:首先利用超定辅助变量乘积矩(0IVPM)的最小特征值确定自回归部分的阶,然后利用协方差矩阵的特征值估计滑动平均部分的阶。

A frame image of a video frequency sequence is read into a postpositional memory zone, and staring position and size information of a tracked object is obtained in the frame, then distribution statistical information of a target signature is extracted to build a gauss mixed model as an object template, a mean vector and a covariance matrix in gauss mixed distribution are used to describe the position and the size of the object, then the next frame image of the video frequency sequence is read into the postpositional memory zone. In a new frame video frequency image, a parameter estimation method is used to obtain object gauss mized model parameters in the current frame in iterative computation and find candidate template similar to the object template, and the final model parameters obtained in iteration are used to update the tracking window for realizing self-adaption of the tracked window.
将视频序列的一帧图像读入缓存区,获得该帧中被跟踪目标的初始位置和尺寸信息,然后提取目标特征的分布统计信息建立高斯混合模型作为目标模板,用高斯混合分布的均值向量和协方差矩阵描述目标的位置和尺寸,再将视频序列下一帧图像读入缓存区,在新一帧视频图像中利用参数估计方法迭代计算当前帧中目标高斯混合模型参数找到与目标模板最相似的候选模板,利用迭代得到的最终模型参数更新跟踪窗口实现跟踪窗宽的自适应。
