Parcial-II

四种图像去噪程序，给原图像分别加上高斯噪声，椒盐噪声，乘性噪声，脉冲噪声后进行去噪，输出去噪后的图像(Four image denoising procedures, to the original image plus Gaussian noise, salt and pepper noise, multiplicative noise, impulse noise the Denoising output denoised image)

VapourSynth-BM3D-master BM3D算法的原创代码，运行速度超快，参考文献《Image Denoising by Sparse 3-D Transform-Domain Collaborative Filtering》(VapourSynth-BM3D-master BM3D original algorithm code, run super-fast, Reference " Image Denoising by Sparse 3-D Transform-Domain Collaborative Filtering" )

本程序实现了基于m-PCNN的医学图像融合算法，即多通道PCNN图像融合。(use for fusion)

说明：  比SSIM更新的图像质量评判算法VSNR(image quality assessment VSNR and its matlab code)

this code is for the paper of image segmentation based on level set methods. in this paper improves Tony Chan s paper and improves the speed.

专门用于测试数码相机的分辨率使用,有实验用图(Specifically for use in testing digital camera resolution)

说明：  1. 对图像进行傅里叶变换。 2. 根据傅里叶变换的结果去除图像的竖条纹噪声。 3. 对图像进行傅里叶逆变换，得到分割图像。 (1. For the image Fourier transform. 2. According to the results of Fourier transform to remove the image of the vertical stripe noise. 3. Inverse Fourier Transform of the images obtained segmented image.)

图像去噪，采用GUI界面形式，里面包括高斯滤波，低通滤波和理想滤波三种方法。(Image denoising, using GUI interface form, which includes Gaussian filtering, low-pass filtering and ideal filtering three methods.)
