Evaluation of Weighted Nuclear Norm Minimization Algorithm for Ultrasound Image Denoising

Algorithm 1

Input: Noisy image

1. Initialize _,

2. For to number of iterations

3.   Regularize in each iteration

4.   For each patch in the image of fixed size

5.      Identify identical patch group

6.      Estimate weight vector

7.      Perform singular value decomposition (SVD)

8.      Obtain the estimate

9. End

10.    Build clean image at the iteration k

11.  End

Output: Filtered image
