使用forstner算子进行图像特征点提取(forstner for feature extraction)

matlab OTSU 简易的大津算法 求最佳阈值的。(matlab simple algorithm seeking Otsu threshold.)

传统的几种图像增强与去噪方法，包括直方图处理，灰度变换，滤波去噪等几类。细分为直方图均衡化，直方图规定化，灰度线性变换，中值滤波，维纳滤波，同态滤波(The traditional methods of image enhancement and denoising include histogram processing, grayscale transformation, filtering and denoising. Subdivided into histogram equalization, histogram specification, gray level linear transformation, median filtering, Wiener filtering, homomorphic filtering)

一种细化的骨架提取算法 可以提高徐璈的处理厚重图像(sgsdgsdgsdgggs skeleton extraction)

说明：  图像梯度计算 遥感图像处理必备 非常实用 欢迎下载(Remote sensing image processing image gradient calculation is very useful are welcome to download necessary)

基于小波阈值法来实现图像去噪，这是小波阈值去噪的程序代码。(Based on wavelet thresholding denoising method to achieve this is wavelet thresholding procedure code.)

说明：  LSB替换隐写软件，该软件能把ASCII码嵌入到图像中，其载体图像是24位的BMP格式图像(LSB replaces steganography software, which can embed ASCII code into image, and its carrier image is 24 bit BMP format image)

压缩感知去噪代码，一种用于去噪的CS的有效代码，简单适用(Compressed sensing denoising code, one for denoising CS valid code, a simple application )
