查询词典 iteration

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。

In other words, a relaxation scheme is equivalent to a fixed-point iteration on a preconditioned system.

Also the reciprocal theorem is invoked and analytical expressions of the Frechet derivatives are derived on the basis of NMM, and resultingly in each iteration the forward modeling is needed to be invoked only once.

为提高速度，采用前述的INMM方法，同时运用互易定理，并导出了基于NMM的Frechet导数解析表达式，这样，每次迭代只需一次正演。

When read returns an empty string, iteration is ended and is not resumable.

当 read返回一个空字符串时，迭代被结束并且不可被恢复。

In SART（Simultaneous Algebraic Reconstruction Technique）,there is no restrict to image space,so the image space's noise will increase after the definite number of iteration.

In this paper, we develop a new algorithm called the sequence subsets SART, which decrease the number of subsets after each iteration. Thus we not only accelerate convergence of the reconstructed image but also recover various frequency components of the reconstructed image in early iterative steps.

本文提出序列子集联合代数重建技术，在每次迭代后减少使用的子集个数，这样在加速图像收敛的同时恢复重建图像的各种频率元素。
