说明：  给仿真信号加入噪声信号，比如白噪声、有色噪声等等(Added to the simulated signal noise signal, such as white noise, colored noise, etc.)

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)

说明：  同时正交分解，也是对MP的改进，实现信号的稀疏分解(At the same time orthogonal decomposition, also MP for improvement, and the signal is sparse decomposition)

说明：  有源电力滤波器是用于动态抑制谐波、补偿无功的新型电力电子装置，控制并主动输出电流的大小、频率和相位，并且快速响应，抵消负载中相应电流，实现了动态跟踪补偿，而且可以既补谐波又补无功和不平衡。(APF:Active power filter)

很好用的FastICA工具箱，以及使用攻略，非常容易入手学习。(Good use of FastICA toolbox, and the use of the Raiders, very easy to start learning.)
