边缘检测算法的一种实现

matlab中dftfilt.m文件函数源代码(Matlab dftfilt.m file function source code)

通过对DXF文件解析，将解析后的数据以列表的形式展示在winform窗体中

说明：  主要用于遥感图像道路信息提取，能得到很好的效果。(It is mainly used to extract road information from remote sensing images and can get good results.)

可见光波长和颜色的对应生成代码，可以保存问为图片(Corresponding to the wavelength of visible light and color to generate code that can be saved to ask for the picture)

利用多尺度高斯函数去除场景的光照分量；然后构造了一种二维伽马函数，利用光照分量的分布特性调整二维伽马函数的参数，降低光照过强区域的亮度值，提高光照过暗区域的亮度值，最终实现对光照不均匀图像的自适应校正处理。(The multi scale Gauss function is used to remove the illumination component of the scene, and then a two-dimensional gamma function is constructed. The parameters of the two-dimensional gamma function are adjusted by the distribution characteristics of the illumination component, the brightness value of the light illuminated region is reduced and the brightness value of the light dark area is improved. Finally, the adaptive correction of the uneven illumination image is realized. Positive treatment.)

平稳移不变小波变换，及图像去噪应用，PSNR, SSIM图像质量评估(stationary wavelet for image denoising)

数字图像处理中常用的标准图像，包括大家所共知的lena等图片的高分辨率版本，推荐大家下载(Commonly used in digital image processing standard images, including all the known to the lena and other high-resolution version of the picture, we recommend downloading)

常规的中值滤波器，在噪声的密度不是很大的情况下效果不错。但是当概率出现的概率较高时，常规的中值滤波处理后，仍然具有噪声点，并丢失了细节和边缘，效果不是很好。 自适应中值滤波器可以尽可能的保护图像中细节信息，避免图像边缘的细化或者粗化。(The conventional median filter works well when the noise density is not very large. However, when the probability of probability is high, the conventional median filter still has noise points, and the details and edges are missing. The result is not very good. The adaptive median filter can protect details in the image as far as possible and avoid thinning or coarsening of the image edges.)

本代码是使用matlab编写的harr特征的代码，值得大家研究和参考(This code is the use of matlab prepared harr characteristics of the code, it is worth study and reference)

说明：  产生水印，并进行基于DCT域的水印嵌入。(Have a watermark and DCT-based watermark embedding domain.)
