DCT

计算img文件夹内所有图像之间的相似度，并根据相似度排序，呈现每个图片的最相似图片结果(calculate the image similarity of each pic in img filedir)

用画笔绘制圆角矩形，椭圆，饼形，并用不同颜色画刷进行填充。(Draw a rounded rectangle, ellipse, pie with a brush, and brush with a different color fill.)

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.)

说明：  对图像纹理特征进行提取，包括灰度共生矩阵、Lbp、小波等(Texture feature extraction of image, including gray level co-occurrence matrix, Lbp, wavelet 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.)

考虑雨衰 阴影 和多径影响，可以广泛的应用于数据预测及数据分析,采用了小波去噪的思想。( Consider shadow rain attenuation and multipath effects Can be widely used in data analysis and forecast data, Using wavelet denoising thought.)

说明：  利用c语言快速实现各类小波变换，案例丰富(Using C language to realize all kinds of wavelet transform quickly, with rich cases)

词袋模型，非常好的参考，有详细说明，希望顺利使用。(The bag of words model, a very good reference, there are detailed instructions, hope to use smoothly.)

利用matlab程序编写的图像分割代码，计算分割后的区域邻接图(Using the image segmentation code written by the matlab program to calculate the neighborhood graph after the segmentation)

这是vtk结合MFC在一个对话框内进行面绘的代码，读入图像的格式为DICOM(vtk This is a combination of the MFC dialog within the code face painting, Reading into the image of the DICOM format)
