查询词典 optimization

The second improvement is to combine the fuzzy optimization model, which has its advantages with view to quantitative problems, with the decision-making method based on fuzzy congruity theory, which has its advantages with view to qualitative problems, thereby a modelthat is more applicable to the practical evaluation of the problems that have both quantitative indices and qualitative indices, or a so-called mixed model is established.

本研究提出了相应的改进方法：一是将基于模糊一致矩阵理论的决策分析方法推广到了多层次的情况，使之适用于多层次、多指标综合评价问题；二是将对定量指标问题具有优越性的模糊优选模型和对定性指标问题具有优越性的基于模糊一致矩阵理论的决策分析方法结合起来，构建了更适合应用于实际综合评价问题既有定量指标又有定性指标的模型，即所谓的混合型模型。

不同於旧有的方法利用单一的圆锥曲面，我们利用多段的圆锥曲面拟合网格以降低误差，并保证同一区块内，圆锥之间的C0连续性，因此我们的演算法可以利用较少的区块，来更精确的拟合网格。

But these methods limited by the expense of computing fundamental matrices and trifocal tensors or of the nonlinear optimization involved in computing epipolar tangencies. Through the studies of the invariants of the single axis motions, computational theories have been developed in this thesis to provide practical solutions for the problem of structure and motion from fitting the corresponding points in the whole sequence to its conic locus or conics for short.

在最近的研究中，一些研究人员利用视觉几何的方法从非定标的图象中对单轴旋转运动进行分析，提出了利用基本矩阵和三焦距张量求解单轴旋转运动中的关键参数——旋转角度的算法，但是该算法需要计算一系列相邻2图象的基本矩阵和一系列相邻3图象的三焦距张量，由于每个基本矩阵的自由度为7，每个三焦距张量的自由度为18，导致算法参数数量非常之大。
