A Modified Iterative Alternating Direction Minimization Algorithm for Impulse Noise Removal in Images
Algorithm 1
Remove impulse noise using PANO.
Initialization: | Input the noise contaminated image , the PANO , | regularization parameter , tolerance of inner loop , and times of | learning similarity is 3. Initialize , , for and . | Main: | Step 1. Obtain the initial guide image from median filtering [1]; | While , | Step 2. Learn similarity in PANO from the guide image [27]; | While , | Step 3. Solve (8); | Step 4. Solve (9); | Step 5. Solve (10); | Step 6. If , , go to Step 3; | otherwise, go to Step 7; | Step 7. , , go to Step 3. | End While | Step 8. , , , Go to Step 2; | End While | Output: |
