C# 放大和缩小图像 实例源码

使用regionprops中BoundingBox功能对图片进行处理获得X,Y的坐标值以及长宽度(Use regionprops the BoundingBox of the image processing functions to obtain X, Y coordinate values and long-width)

说明：  在matlab下实现信号频谱分析：利用快速付里叶变换FFT得到下列信号的频谱，并绘制信号及频图形：1.长2s的方波信号，频率f=10Hz (In matlab signal spectrum analysis: the fast in leaf transform FFT get pay of spectrum, the signal and drew the signal and frequency graphics: 1. The long 2s, frequency f = square wave signal 10Hz )

这是香港大学沙威博士写的压缩感知引论及相应的OMP算法。(This is written by the University of Hong Kong, Dr Savit compressed sensing cited dealt with the OMP algorithm.)

该算法实现了通过霍夫变换提取直线和圆，希望对大家有帮助(This algorithm can extract line and circle through hough conversion.)

此代码应用于图像分割，是基于类间方差的大津法求分割阈值(This code applies to image segmentation is based on the variance between two classes of Otsu threshold segmentation uated)

解决散斑图像的重建问题,主要是使用了相位恢复算法(to study the picture problem)

说明：  对JPEG细粒度 图像质量评价的算法评估。SSIM的KLCC（肯德尔秩相关系数）。(Algorithmic evaluation of JPEG fine-grained image quality evaluation. KLCC (Kendall Rank Correlation Coefficient) of SSIM.)

计算波导的matlab程序，主要是传输矩阵方法(Waveguide matlab calculation programs)

计算局部形状描述符梯度方向直方图（HOG），直接输入图像即可用。(Calculate the local shape descriptors gradient orientation histogram (HOG), the input image can be used directly.)
