It can obtain 1. aspect ratio 2. rectangularity 3. roundness 4. area concave-convex ratio 5. circumference concave-convex ratio 6. sphericity 7. eccentricity 8. shape parameters.)

说明：  matlab编写的直线检测算法，能够有效的提取出直线。和matlab自带的hough变换实现的同样的功能(matlab prepared in a straight line detection algorithm can effectively extract the straight line. And the hough transform matlab own to achieve the same function)

SVT 低秩矩阵恢复，可用于稀疏表示、图像恢复(SVT for low rank matrix completion)

说明：  本例程可以通过肤色进行人脸检测，同时包含一些对图像的基本处理方法，并集成了人脸识别的GUI界面。(This routine can detect face by skin color, and also includes some basic processing methods for image, and integrates GUI interface of face recognition.)

说明：  图片的加法运算减法运算乘法运算除法运算和四则运算(Four Operations of Addition, Subtraction, Multiplication and Multiplication of Pictures)

裁剪shape文件，使用idl编程实现，就是一个功能，编译以后可以直接调用这个函数(Clipping shape file, using idl programming, is a function, after compiling can directly call this function)

完成水果的尺寸形状表面缺陷的判别，BP神经网络的训练判别表面缺陷(Fruit size, shape and surface defects are identified. BP neural network is used to identify surface defects.)

说明：  采用模糊C均值聚类算法求到欧式距离和方差，对数据集（特征+标签）进行分类并得到分类准确率(The Euclidean distance and variance are calculated by fuzzy c-means clustering algorithm, and the data set (feature + label) is classified and the classification accuracy is obtained)

运用计算机图形学的知识，采用4阶B样条基函数，节点向量取为[0,0,0,0,1/4,2/4,3/4,1,1,1,1] 先绘制控制多边形，再用分段直线段绘制B样条曲线(Using the knowledge of computer graphics, the 4 order B spline basis function is used, and the node vector is taken as [0,0,0,0,1/4,2/4,3/4,1,1,1,1]. First, draw the control polygon and draw the B spline curve by piecewise straight line segments.)

说明：  图像预处理以及提取图像的Tamura 纹理特征(Image preprocessing and Tamura texture feature extraction)
