基于MATLAB的图像信息隐藏算法研究与实现_陈小娥

亚像素边缘检测的matlab代码，比一般的边缘检测代码精确(Sub-pixel edge detection matlab code)

工业摄影测量技术，利用matlab编写数字图像处理界面，包含相关手写算法，包括canny算子，LOG算子，canny滤波，高低通滤波，butterworth高低通滤波，数米粒，全方位图展开技术……(write a GUI of digital image processing with matlab，including canny operator，LOG operator，Lowpass and highpass filter，etc)

这是一个实时提升小波，滤波程序，它可以滤除噪声(This is lift wavlet,denoting the note process)

目前MATLAB里边对于多点计算仿射矩阵普遍采用RANSAC法，但是比较麻烦计算量也相对较大，通过最小二乘法来进行仿射矩阵的估计能够大大提高该效率，所以奉上自己在实验室写的仿射矩阵估计函数，来弥补matlab函数库在这方面的不足。(The MATLAB inside for calculating affine matrix commonly used RANSAC method, but more trouble calculation is relatively large, estimated by the least squares method to the affine matrix can greatly improve the efficiency, so give yourself in laboratory to write the estimated affine matrix function, to compensate for the lack of MATLAB Library in this area.)

图像处理中的一种降噪方法，对去掉图像的噪声有很好的效果(Image processing method of a noise reduction of images to remove the effect of noise has a very good)

实现了图像的灰度化并进一步用于视频监视控，一些自适应信号处理的算法，计算加权加速度。( Achieve a grayscale image and further control for video surveillance, Some adaptive signal processing algorithms, Weighted acceleration.)

使用函数wbmpen获取小波去噪阈值,然后使用函数wbmpen实现信号去噪(Use function wbmpen threshold for wavelet de-noising, and then use the function wbmpen for signal denoising)

基于retinex理论的图象增强处理，一种新型的算法，效果挺好(Based on the Retinex theory of image enhancement processing, a new type of algorithm, the effect of good)

用所写算子进行边缘检测，对matlab自身图片进行分析，其中的suanzi.m是自定义的边缘检测算子(operator with written for edge detection, right Matlab own photo analysis suanzi.m which is the definition of edge detection operator)

说明：  meanshift算法实现目标的跟踪，由视频序列文件中提取出第一帧，定义目标区域，进行跟踪，动态显示跟踪结果(meanshift target tracking algorithm, by the video sequence documents to extract the first frame, the definition of the target area, tracking, tracking the results of dynamic display)
