Description: 图像颜色特征提取（三阶矩）完整代码；stricker和0reng0提出了颜色矩的方法，颜色矩是一种简单有效的颜色特征表示方法，有一阶矩(均值)、二阶矩(标准差)和三阶矩(斜度)等，由于颜色信息主要分布于低阶矩中，所以用一阶矩，二阶矩和三阶矩足以表达图像的颜色分布，颜色矩已证明可有效地表示图像中的颜色分布(Image color feature extraction (three moments) complete code;Stricker and 0reng0 proposed a method of color moments. Color moments are a simple and effective color feature representation method. There are first order moment (mean), two order moment (standard deviation) and three order moment (slope). Because the color information is mainly distributed in the low order moment, the color distribution of the image is expressed with the first moment, the two order moment and the three order moment. Color moments have proved effective in representing color distribution in images.)

Description: 其目标是将大量黑白矩形像素显示器中的每一个识别为英文字母中的26个大写字母之一。字符图像基于20种不同的字体，并且这20种字体中的每个字母随机失真以产生20,000个独特刺激的文件。每个刺激被转换成16个基本的数字属性（统计矩和边缘计数），然后将其缩放以适合从0到15的整数值范围。我们通常在前16000个项目上进行训练，然后使用结果模型预测剩余的4000个字母类别。请参阅上面引用的文章以获取更多详细信息。(The objective is to identify each of a large number of black-and-white rectangular pixel displays as one of the 26 capital letters in the English alphabet. The character images were based on 20 different fonts and each letter within these 20 fonts was randomly distorted to produce a file of 20,000 unique stimuli. Each stimulus was converted into 16 primitive numerical attributes (statistical moments and edge counts) which were then scaled to fit into a range of integer values from 0 through 15. We typically train on the first 16000 items and then use the resulting model to predict the letter category for the remaining 4000. See the article cited above for more details.)

Description: 将绳索看成无弹性变形，利用牛顿拉格朗日建立其动力学模型，拉格朗日是在求解并联机构动力学中是非常经典的力学变形，结合了动量守恒和能量守恒。拉格朗日方法通过一系列广义坐标确切地阐述了运动方程，他在一开始就消除了所有的或者部分不关心的反作用力和力矩，使用广义的坐标可以适当的简化并联机构中动力学的分析。 势能和动能之差为其动力学的拉格朗日函数。(he rope is regarded as inelastic deformation, and its dynamic model is established by Newton Lagrange. Lagrange is a very classical mechanical deformation in solving the dynamics of parallel mechanism, which combines the conservation of momentum and energy. Lagrange's method describes the equation of motion exactly through a series of generalized coordinates. He eliminated all or part of the unconcerned reaction forces and moments at the beginning. Using generalized coordinates can properly simplify the dynamic analysis of parallel mechanism. The difference between potential energy and kinetic energy is the Lagrangian function of its dynamics.)
