In temporal segmentation a statistical model is used to automatically separate the moving areas from the background in a general video sequence . the spatial segmentation bases on the results of temporal segmentation and using region - growing algorithm in rgb space can locate precise boundary of moving object . lastly , using segment moving object as the initial model , moving object can be tracked by matching an image to a model based on hausdorff distance on a sequence of video , and the model is updated every frame to accommodate for changes in shape 时间分割中采用连续帧间差的统计假设检验,确定运动对象的位置,自动地分离出运动区域与背景区域;空间分割中则采用基于颜色的区域增长算法来精确地提取运动对象的轮廓;最后,将提取到的运动对象作为模板,对后续的视频序列,用基于hausdorff距离度量匹配,来跟踪并提取后续帧中运动对象。
This paper analyzed the relationship between the model space , initial models , local minimization solutions , global minimization solution etc . in the geophysical inverse problem and the state space , particle state , stationary state , excited states , ground state etc . in the atomic transition based on the similarity of the procedure of iterative optimization for geophysical inverse problem and those for atomic transition 摘要详细研究了一般地球物理反问题的迭代优化求解过程与物理学中原子跃迁过程的对应关系,建立了反演问题中模型空间、初始模型、局部极值模型、最优化模型等与原子的态空间、定态、激发态、基态等的对应关系。
Multi - channel deconvolution , based on multi - channel signal analysis , is presented to recover receiver function from three - component teleseismic p waveforms clustered within certain backazimuth and epicenter distance , to increase the resolution of receiver function . wavelet inversion is also introduced to broadband receiver function , to solve for nonuniqueness cased by linear approximation of nonlinear problem , and broadband receiver function is decomposed into multi - resolution versions , and the inversion result for the low - resolution version is iteratively taken as the initial model for the high - resolution , and gradually obtain the inversion model for broadband receiver function 为克服广义线性反演对初始模型的依赖性,并保持其快速收敛的特点,本文首次将小波变换引入到接收函数波形反演,将接收函数分解到不同的分辨尺度上,分别进行广义线性反演,并将低分辨率的反演结果作为高分辨率反演的初始模型,渐近地获取宽频带接收函数的模型,克服了非线性问题线性化带来的非唯一性。
When calculating the cost of edge collapse , we consider the influence of edge length and surface curvature . and , the position of the new vertex is selected from the veytexes of the edge collapsed , this can not only preserve the initial model shape , but also reduce the calculation of cpu and meet real - time rendering of virtual environment 在折叠边的代价估计中,均衡考虑了多边形边的长度和多边形表面曲率影响;折叠边的顶西北工业大学博士学位论文点位置从折叠边的顶点中选取,既有助于保留了初始模型的形状,又减少运算量,满足快速绘制的需求。
