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)

该程序是一个数值模拟程序，模型是新凯恩斯模型，该程序主要模拟在新凯恩斯模型中发生技术冲击，对经济变量的影响(The program is a simulation program, the model is New Keynesian model, the main simulation program occurred in the New Keynesian model of technological impact, the impact of economic variables)

格子Boltzmann多组分多相流模型，来模拟相分离(Lattice Boltzmann Model for multi-compent and multiphase)

计算样本数据集的峰度系数和峭度系数的代码，比较实用(Kurtosis and kurtosis coefficient code to calculate sample data sets, more practical)

MATLAB下的四旋翼飞行器建模程序，可以用于仿真四旋翼模型(This is a UAV model under the MATLAB program, The UAV model can be used in the simulation.)

说明：  Matlab仿真Airy光束相位图，有效(MATLAB simulation of Airy beam phase diagram, effective)

用六种算子(分别是gabor、拉普拉斯、priwitt、robert、sobel、wallis),对三种图象进行边缘检测比较，强烈推荐哦，是本人的毕业设计中的关键程序 85353167bianyuan_jiance_bijiao
