When the lens is focused on the hyperfocal distance, the depth of field extends from half the hyperfocal distance to infinity.

当镜头聚焦在超远焦端时景深从超远焦端延伸至无限远，也就是说从超远焦到无限远的距离都是清晰的成像

There is nonlinearity between the distance of the object and the distance of its image in the laser triangulation.

由于激光三角法具有原理上的非线性，为了便于测量和控制，需要进行补偿。

That is, the objective distance can be changed freely while keeping the image distance constant and vice versa.

并给出了多层光子晶体平板的成像结果，实现了正方形三角形混合晶格光子晶体平板近远场成像。

A line considered a limit to a curve in the sense that the perpendicular distance from a moving point on the curve to the line approaches zero as the point moves an infinite distance from the origin.

渐近线与曲线极限相关的一条直线，当曲线上某动点沿该曲线的一个分支移向无穷远时，动点到该直线的垂直距离趋于零

The difficulty lies in the fact that it is hard to find a signature model that is insusceptible to intro-classes distance and at the same time is sensitive to inter-classes distance.

摘要离线中文签名的自动验证是一个极其复杂的问题，其困难主要在于难以建立能够容忍类内偏移同时对类间区别相对敏感的签名模型。

Based on the principle of Otsu method with maximum variance between threshold algorithm of image segmentation, an improved method derived from Otsu algorithm is put forward, which combines interclass distance with intraclass distance, a partial recursive algorithm is used to search optimum threshold.

基于最大类间方差阈值图像分割算法的基本原理，然后结合目标与背景两类之间间距和类内距离对图像分割效果的影响，提出了一种改进的最大类间方差法，运用递归思想局部搜索图像的最佳阈值。

Followed by the decomposition phase is optimal feature subset selection, in which the optimal feature subset acquired the best divergence is obtained according to interclass/intraclass distance of the training samples. This procedure is implemented by a Genetic Algorithm, with each possible feature subset encoded as chromosome. Fitness scores in GA are calculated and evaluated based on Jeffries-Matusita distance of the selected training samples.
