说明：  在我们的移动端开发中，需要用到折线图，本篇内容就是用flutter写的一个折线图例程。(In the development of our mobile terminal, we need to use the line chart. This article is a line chart routine written by flutter.)

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.)

医学图像处理，实现图像分割，一基于区域生长法；二基于最佳阈值分割(Medical image processing, and image segmentation, one based on region growing method two thresholding based on the best)

多尺度多方向性的剪切波Shearlet变换优于小波变换，里面包含很多例子，可以直接运行，可以用于图像去噪，分割，增强等，是一个优于小波的图像稀疏表示工具(Shearlet transform of multi-scale and multi-directional shear wave is better than wavelet transform. It contains many examples and can run directly. It can be used for image denoising, segmentation and enhancement. It is an image sparse representation tool better than wavelet transform.)

为方便土地利用总体规划编制单位制作土地利用总体规划图件，针对市、县、乡三级土地利用总体规划制图，制作市、县、乡土地利用总体规划必选图件的图式符号库。该图式符号库适用于ArcGIS软件平台下的图件制作(In order to facilitate the land use master planning units to make land use master plan maps, for the city, county, Township three-level land use master plan mapping, the city, county, Township land use master plan must be selected map schema symbol library. The graphic symbol library is suitable for map making under the ArcGIS software platform.)

说明：  本程序主要用于进行CCD相机内外参标定，摄影测量。(This procedure is mainly used for calibration and photogrammetry of internal and external parameters of CCD camera.)

数字图象处理算法的演示，包括：图象的DFT和逆DFT，图象的FFT和逆FFT，在图象中加入正弦噪声，图象的模板运算实现图象平滑和锐化等等。(digital image processing algorithms demo, including : Image DFT and inverse DFT, FFT image and inverse FFT, in the image by adding sinusoidal noise, the template image Operational Image sharpening and smoothing and so on.)

图像的自动多阈值分割，可以进行灰度图像的自动分割。(Automatic multi-image threshold segmentation, gray-scale images can be automatically split.)

基于harris兴趣点的图像检索程序。先特征提取，进而进行特征匹配，最后还有结果的返回。(Harris points of interest based on image retrieval process. First feature extraction, feature matching and then carried out and, finally, the results returned.)

说明：  这是一个增强的nsst程序，采用matlab编程，可以运行。(This is an enhanced NSST program, using MATLAB programming, can run.)
