60轨CAD断面图，严格按照国家标准作图，60轨CAD断面图(Cross-sectional drawing of 60-rail CAD)

说明：  行星齿轮动力学分析微分方程的matlab中ode45求解(The solution of the differential equation of planetary gear dynamic analysis by ode45 in MATLAB)

使用帧差法、均值法和混合高斯模型对背景进行去除、提取前景信息。来源于2017年研究生数学建模比赛D题。(The background information is removed and the foreground information is extracted by frame difference method, mean value method and hybrid Gauss model. D graduate from the 2017 mathematical modeling contest.)

这次上传的代码是关于MRI Brain Scan_segmentation用的代码，希望能对大家有用(this code is uploaded on Scan_segmentation Brain MRI of the code, we hope that the useful)

说明：  经典的图像像素层融合算法-Brovery.程序输入中两幅图像需经过配准，大小一致。matlab代码内有详细的注释。其他像素层融合算法可仿照此修改即可。需要配对图像和运行结果、其它基于小波融合代码的可发邮件给我。非常乐意和大家共享编程乐趣。(classic image pixel level fusion algorithm-Brovery. Import procedures which require a two image registration, the same size. Matlab code with detailed comments. Other pixel level fusion algorithm can be modeled on this amendment. Image matching needs and operating results, the other based on wavelet integration code can mail it to me. Very happy to share programming and fun.)

1. 将真彩位图转化成各色或黑白位图，进行二值化(支持多种抖动方法)处理后的位图，效果和速度极佳。 2. 将真彩或黑白位图进行 90度 , 180 度 ,270 度 高速度旋转。 (1. The true color bitmap into a colored or black and white bitmap to binary (supports multiple dithering methods) treated bitmap, effects and excellent speed. 2. The true color or black and white bitmap to 90 degrees, 180 degrees, 270-degree high-speed rotation.)

灰度共生矩阵和灰度梯度共生矩阵纹理提取，能够计算纹理的多个测度(Gray Level Co-occurrence matrix and gray-gradient co-occurrence matrix texture extraction)

说明：  PCA图像融合算法，提取主成分来对图像进行融合,感兴趣的可以看看。(Principal component analysis Image fusion algorithm, extraction of principal components to image fusion.Those of you who are interested can take a look.)

说明：  热电厂CAD图纸资料，在CAD软件中绘制(Thermal power plant CAD drawings)

JPEG2000图像压缩算法，可计算压缩比，MSE，PSNR等参数(JPEG2000 image compression algorithm, you can calculate the compression ratio, MSE, PSNR and other parameters)
