颜色预测模型评估,印刷品质量检测技术,实现光谱分析，检测色彩偏差(color model assessment, print quality inspection technology, spectrum analysis, color deviation detection)

此M文件主要利用区域生长和边缘检测进行图像分割(image segment by region grow )

说明：  此文件为非均匀B样条曲线反求控制点再插值为曲线(This file is a non-uniform B-spline curve. The control points are inverted and then interpolated into a curve)

这是一个人脸识别的程序，先对图像预处理，然后用PCA进行特征提取。(This is a face recognition process, first on the image pre-processing, and then use PCA for feature extraction.)

matlab实现的小波图像压缩，序列图像压缩处理，效果很理想(Matlab realization of wavelet image compression, image compression sequence, and the effect is very satisfactory)

说明：  Matlab实现简单图形处理，包括灰度、亮度、对比度变化等功能(Implement Simple Graphics Processing with matlab. Equipped with the function of gray level,brighteness and contrast ratio transfotmation.)

输出不同截止频率的滤波图像和不同截止频率的滤波图像的幅度谱。(Different filter images are output for different cutoff frequencies.)

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：  基于MATLAB的行人检测。直接运行imhogtrace主程序，即可得到运行结果。针对不同的图像，需要调整参数，我放的这张图，虽然效果不好，但是可以提供参考意义(Pedestrian detection based on MATLAB. Run the main program of imhogtrace directly to get the running result. For different images, parameters need to be adjusted. Although the effect of this picture I put is not good, it can provide reference significance)

说明：  Fienup的混合输入输出算法，是一种迭代算法，用来求相位的算法HIO(Fienup's hybrid input and output algorithm is an iterative algorithm used to find the phase algorithm HIO)
