Les méthodes géométriques sont les méthodes les plus répandues en simulation indoor. On a cité les principales familles de ces méthodes. Il s’avère qu’il n’existe pas de meilleures méthodes que d autres. En effet, le choix d’une méthode par rapport à une autre dépend des objectifs principaux qui sont fixés au début du travail. Il est donc fondamental de faire un compromis entre le nombre de rayons à calculer et la complexité de calcul.

暑假作业，千方百计查询资料才做出来的，包括相关文章和代码，希望对其他人有用(Summer homework, do everything possible to query data to do it, including related articles and code, and I hope its useful to others)

matlab code for image processing

matlab变成实现prony算法，自动提取符合信号中分量的频率、幅值、相位、衰减系数等参数，可以实现数据拟合(matlab become realized prony algorithms automatically extract the parameters frequency, amplitude, phase, in line with the signal attenuation coefficient component, you can achieve data fitting)

matlab的二次拟合程序源码与大家分享！直接是M文件！(matlab secondary source fitting procedures to share with you! M file directly!)

Edge detection result should be enhanced using linear method like Median filter to remove the garbage around the pupil to gain clear pupil to determine perfect centre. Get the centre of the pupil by counting the number of black pixels (zero value) of each column and row. Then get each row and column that has the maximum number of these black pixels. Then determine the center by simple calculation according to the image coordinate to set it correct on the image, consequently we can determine the radius of the pupil. Thus we can find the pupillary boundary (inner). A similar procedure is extended by using a coarse scale to locate the outer boundary (limbus) which can be apparent by using the mid-point algorithms of circle and ellipse.

利用PLSI算法自动对一个文档集进行聚类，需要调节聚类的维度K值，从而得到最大的likelihood(PLSI automatically using an algorithm for clustering document set needs to be adjusted to the dimension value of K clusters, to obtain the maximum likelihood)

python-wapiti is a python wrapper for wapiti (http://wapiti.limsi.fr), a very nice sequence labeling tool with support for maxent models, maximum entropy Markov models and linear-chain CRF.
