摘　要:针对茄子图像的灰度和颜色特点,利用MATLAB中丰富的图像处理函数,分别进行了色差分割和色调分割。在 色调分割中,采用了自动选取阈值的Otsu法。在去除残留噪音的处理中,采用标注的方法对二值图像的各连通区域进行面积 统计。保留最大面积的区域,从而使分割效果大大改善。利用多参数来衡量分割效果,使评价做到最大程度的客观、合理。(Based on the gray- level and color characteristics of eggp lant image, hue and color- difference segmentation were conducted by using the rich image p rocessing functions embedded inMATLAB. The auto threshold- adap tivemethod ofOtsu operation was specially used for hue segmentation. And upon the elimination of the residue noise, labelingmethod for statistical calculation was introduced for the connected regions of the binary image. Themaximum areaswere p reserved to imp rove segmentation effects. In addi2 tion, multi- indiceswere app lied to assess the effect of segmentation, in order to get impersonal and reasonable assessment)

bpsk信号解调算法的Matlab实现，比较简单的例子(demodulation of bpsk)

误码率计算程序，可以实现简单的误码率计算。对初学者有用(bit error rate calculation program, can achieve a simple error rate. Useful for beginners)

说明：  自己写的一个fastica程序，分离结果还可以，可用(Write a fastica own procedures, the separation results can also be used)

function [a,b] = pade(x,p,q) PADE Model a signal using the Pade approximation method ---- Usage: [a,b] = pade(x,p,q) The input sequence x is modeled as the unit sample response of a filter having a system function of the form H(z) = B(z)/A(z) The polynomials B(z) and A(z) are formed from the vectors b=[b(0), b(1), ... b(q)] a=[1 , a(1), ... a(p)] The input q defines the number of zeros in the model and p defines the number of poles.

Apply the standard QR-decomposition based LSL algorithm using angle-normalized error to predict/estimate complex-valued processes.

这是我在学习过程使用到的一些程序，希望对大家有所帮助!(This is what I used in the learning process some of the procedures, I hope all of you to help!)
