Image Noise Removal Method Based on Improved Nonlocal Mean Algorithm

Algorithm 2

Improved NLM algorithm weight update steps.

	Initialize, select any 2 pixels i and j
(1)	Set minimum radius d = dmin
(2)	If d ≤ dmax, calculate Ku, otherwise go to step 6
(3)	If j ∉ Ku, go to step 6
(4)	If , then let d = d + 1, and then go to step 2
(5)	Let , end
(6)	Let , end
