2010射线跟踪课件3 (1)

此程序为用于主成分分析的matlab程序,可以输出贡献率及画出二维散点图(This program for principal component analysis of matlab, can output contribution rate and draw a 2 d scatter plot)

说明：  衍射光学光束整形元件设计 目标：在透镜后焦面上实现图形的光强分布 实现： 1、波长、衍射光学元件口径、形状、入射波前、二维目标分布及尺寸等都可自行设定； 2、对相位进行8台阶量化，重新计算； 3、更换输出面的采样间隔，重新计算。(Design of Diffraction Optical Beam Shaping Element Objective: To realize the intensity distribution of the pattern on the focal plane behind the lens. Realization: 1. Wavelength, aperture, shape, incident wavefront, two-dimensional target distribution and size of diffractive optical elements can be set by themselves. 2. The phase is quantized by 8 steps and recalculated. 3. Replace the sampling interval of the output surface and recalculate it.)

DSL椭圆检测算法，输入待测坐标，返回椭圆参数(Direct Least Squares ellipse fittness matlab source code. developed byFitzgibbon)

掌握OpenGL中的矩阵变换、模型视图变换及投影变换。(The perspective projection, main view, overhead view and side view of the space tetrahedron shown in Figure 7-41 of the textbook P228 are displayed in four viewing areas using the multi-view area in OpenGL.)

scikit-image: Image processing in Python：Python编写的图像处理程序，可直接调用，是学习python图像处理的很好参考。(scikit-image: Image processing in Python：Image processing program written in Python, can be called directly, is to learn Python a good reference to the image processing.)

车牌去模糊。执行后可清晰地看到车牌号码。效果很好的~~(License plate to go fuzzy. After the implementation of number plates can be clearly seen)

可以识别图像的边缘，提取图像边缘轮廓，且程序简单易懂，方便初学者学习。(You can recognize the edges of images.)

投影机边缘融合软件，可以仿真几何变换，羽化(Edgeblend simulation sofeware)

EM算法。问题背景是，有N条长为L的DNA序列，每条序列里面有一条长尾K的目标序列，但不知道他的位置，目标序列内的核苷酸服从foreground product multinomial distribution，非目标序列服从background multinomial distribution，改程序意在求解两种分布的参数。(EM algorithm. Background to the issue is that there are N pieces of length L of DNA sequences, each sequence which has a target sequence Nagao K, but do not know his position, the target nucleotide sequence within obedience foreground product multinomial distribution, non-target sequence obey background multinomial distribution, the program is intended to change the parameters in solving the two distributions.)
