Our experiments show that DSNR of different images in the same scene changes congruously with PSNR, thus can be used to evaluate the quality of decompressed images and image sequences.

实验证明，在相同场景中DSNR能较好地反映PSNR的变化，因而可以用于对同一图象的不同解压缩图象以及图象序列的评价。

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。

Connected component detection is an elementary and time-consuming operation in digital image processing. It is widely applied in pattern recognition, characteristic extraction, image understanding and so on.

连通检测是计算机数字图象处理中一个重要的基本操作，它在模式识别、图象理解、图象特征提取等方面有着广泛的用途。

As early as in the Book of "Changes □ copulative" have the theories of "Taken objects from view"and "Drow objects as it is".This several brief words is a summary of the integrity of a creative process, and the purpose of creation is through the appearance of things to express the essence of it, the word "image" was then bred.

早在《周易？系辞》中已有"观物取象"、"立象以尽意"之说，这简短的几个字概括了一个创作的完整的过程，而创作的目的便是在"象"中"以尽"其"意"，"意象"一词便应用而生。

The two stage method by-passes the correspondence problem and ill-posed problem encountered in the general motion analysis, and avoids the local minimum problem of the spatial-constrain-based iteration method.

本文推广了全景图象方法和外极面图象方法，从而使之能适用于具有抖动的图象序列分析，并避免了一般运动视觉方法的不适定问题和特征对应问题、基于空域约束的迭代方法的局部最小化等问题。

The general rule I learned from my cytopathology fellowship is that if a thyroid neoplasm looks not perfect for papillary carcinoma, follicular neoplasm, or Hurthle cell neoplasm, think about medullary carcinoma.

我从细胞同行那学习的经验是这样的，如果一个甲状腺肿瘤不完全象乳头癌，不完全象滤泡性肿瘤，也不完全象嗜酸细胞性肿瘤，这个时候，可能就是髓样癌。

He can be as accurate as a slate roof and as clear as a plate glass window and yet have no more life in him than a billboard or a declension.

美国 教授 Canby 尝言一个人尽可以准确得象石板屋顶，清楚得象玻璃窗户而照旧象广告牌，词尾表一样的不具一线生气。

Using the conformational search model of hyperchem, we have searched low energy conformations of α-alanine by the parameter of the dihedral angle.

用Hyperchem软件中的构象搜寻模块，对α-丙氨酸进行系统构象搜索，寻找分子低能构象。

From the mixed pixels distribution map calculated, mixed pixels mainly appear at the western coast of Bohai sea and the edges of the drift ice. Furthermore, these two areas are the areas where sea ice is fairly sparse and the mixed pixels, and therefore, easily appears at those areas. Consequently, it turns out that the method for mixed pixels detecting is effective.

从提取的结果来看，混合象元主要分布在渤海西岸和流冰外缘区域，而这两个海区是海冰分布稀疏的区域，容易出现冰水混合象元，这证明本文的混合象元的确定方法是符合实际的。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
