Algorithm 2: Transformation algorithm for the grayscale image to remove noise
	Input: A path to a dataset image
	Output: A set of denoised images
	Start  Set data an empty list [ ]  For I in image data where i integer numbers range from 0 to n.  For each pixel of a single image  Calculate Normalization function (11)  Evaluate weighted function Equation (12)  Calculate non-local means Equation (10)  data.append[denoised image]  End For  End For  End
