数学建模仿真maple的教程，很多人都用matlab进行科学研究，其实数值计算功能最强大的是maple，几个语句就能实现matlab很难实现的数学运算，这本书很经典，最总要的是Word版本，很方便移植到程序上验证的哦(Mathematical modeling and simulation maple tutorial, many people are using matlab for scientific research, in fact, the most powerful numerical calculation is maple, several statements can be very difficult to achieve matlab mathematical operations, this book is classic, the best always the Word version, it is easy to transplant procedure validation Oh)

计算关联度，本方法使用的是归一化的方法，和传统的经典关联度计算方法相比较，增加了对各个权重的分析和计算，使结果更加有说服力。(Correlation calculation, this method uses the normalized method, and the traditional classical correlation method compared to an increase of weights of the various analysis and calculations makes the results more convincing.)

这篇文章不错 关于数字图像的噪声及其去噪的几种方法研究(Good article on the digital image noise and its several methods of denoising)

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.

在SENSE成像中如何将中间图像转化为最终图像，就要用到这个程序(Using specfied sampling vector to generate a 2D aliasing matrix. The sampling vector is a vector of n-entries of either 0 or 1, where 0 indicates no k-space line acquisition and 1 indicates k-space line is acquired in the accelerated scan. For example, a sampling vector of [0 1 0 1 0 1 0 1 0 1] indicate the 2-fold acceleration with 8 phase encoding lines. The aliasing matrix is calculated based on Fourier imaging)
