Query: A Total Variation Denoising Method Based on Median Filter and Phase
  Consistency   The total variation method is widely used in image noise suppression.
However, this method is easy to cause the loss of image details, and it is also
sensitive to parameters such as iteration time. In this work, the total
variation method has been modified using a diffusion rate adjuster based on the
phase congruency and a fusion filter of median filter and phase consistency
boundary, which is called the MPC-TV method. Experimental results indicate that
MPC-TV method is effective in noise suppression, especially for the removing of
speckle noise, and it can also improve the robustness of iteration time of TV
method on noise with different variance.
