集装箱号码的定位算法，对于字母数字有较好的定位效果，为进一步的号码分割识别奠定了基础-location algorithm for extraction of codes in containers

OTSU方法计算图像二值化的自适应阈值，OTSU 算法可以说是自适应计算单阈值（用来转换灰度图像为二值图像）的简单高效方法。下面的代码最早由 Ryan Dibble提供，此后经过多人Joerg.Schulenburg, R.Z.Liu 等修改，补正。算法对输入的灰度图像的直方图进行分析，将直方图分成两个部分，使得两部分之间的距离最大。划分点就是求得的阈值。都是老外写的，经典哦。-OTSU images calculated value of the two adaptive threshold, OTSU algorithm can be calculated adaptive threshold (for conversion to gray scale images binary images), a simple and efficient manner. The following code from the earliest to provide Ryan Dibble, after a more than Joerg.Schulenburg, R. Z. Liu amend the correction. Algorithm for the importation of gray-scale image histogram analysis of histogram is divided into two parts, Part 2 makes the distance between the largest. Demarcation point out the threshold. Foreigners are written in the classical oh.

现图形学中画直线，园和圆弧以及直线裁剪，区域填充等功能 1． 对于画直线，只需知道起点和终点即可。在工作区间中按下鼠标（即选择起点），拖动至另一处松开（终点），即得到直线。 2． 画圆需要圆心坐标、半径、及起始角和终止角，至于实验要求的画1/4圆弧，可设起始角=0，终止角=45，若要画整个圆弧起始角和终止角分别为0和360即可。-Graphics are painting a straight line, arc, as well as garden and cut a straight line, filled with features such as region 1. For painting a straight line, just know that you can start and finish. Interval in the work of the mouse click (that is, to choose the starting point), drag to another release (the end), that is to be a straight line. 2. Drawcircle need to center coordinates, radius, and the termination of the initial angle and angle, as required by experimental painting 1/4 arc, the starting angle can be set = 0, terminate the angle = 45, in order to draw the whole arc start angle and termination angle is 0 and 360, respectively, can be.
