代码说明:

  对Lena图先进行jpeg压缩,再对压缩后的图像分别进行小波软阈值去噪和非抽样硬阈值去噪,比较两种去噪方案,非抽样硬阈值有更好的效果。这是根据一篇外文文献来进行编程的,最后有图像对比结果。(According to the paper of OPTIMAL WAVELET THRESHOLDING FOR VARIOUS CODING SCHEMES ,I firstly compresse the Lena picture using the jpeg method ,then respectivly denoise it using the wavelet soft-thresholding method and the undecimated DWT hard-thresholding method.Comparing the two method ,we can find the undecimated DWT hard-thresholding have a better result.)

  • mtv
    用TV算法实现图像去噪,包含TV,PM模型等(in this MTV, the diffusion is along the edge direction of the original noisy image(maybe its smoothed version using a Gaussian filter of small scale),it can preserve edge and suppress staircase very well.)
