Wavelet-thresholding

C# 给图片添加水印 图片类型转换 例子

对于叶片面积的计算，进行图像预处理，灰度转换、直方图、去噪声等，最终计算出叶片面积的像素和。(For the calculation of leaf area, image pre-processing, gray-scale conversion, histogram, to noise, etc., and ultimately calculate the leaf area and the pixels.)

对图像目标识别和提取，主要通过改进非线性阈值分割实现(For image target recognition and extraction, the main method is to improve the non-linear threshold segmentation.)

近似熵算法对脑电信号进行特征提取的一些材料(Some materials approximate entropy algorithm for EEG feature extraction)

进行图像的特征提取，为图像拼接做准备，matlab(Feature extraction of image)

一些图象处理及机器视觉的matlib工具，例程，有ransac算法，求单应矩阵等等。(some image processing and machine vision matlib tools, routines, ransac algorithm, should seek single matrix, and so on.)

说明：  该代码为Harris角点检测，两帧图像匹配的matlab代码(The code for Harris corner detection, two images matching matlab code)

说明：  区域生长法进行图像分割，通过选取合适的种子点，将感兴趣区域分割出来。(The region growing method is used for image segmentation, and the region of interest is segmented by selecting appropriate seed points.)

用于计算图像的频率响应，即SFR或者MTF(Can be used to calculate the image frequency response, namely SFR or MTF )

说明：  matlab编写的共轭梯度法，用来解决非线性优化问题(matlab prepared by the conjugate gradient method is used to solve nonlinear optimization problems)
