1. Choose the first pixel. Having it as the center pixel i have to form a 3x3 window. [Being the first pixel i've padded the Matrix with Zeros]
2. If that center Pixel is Noise Pixel it's location should be returned with all its neighborhood pixels. I will convert this 3x3 Matrix into a 1-D array and do my calculations to correct the corrupted pixels.
Here i'm struggling in designing the sliding 3x3 window to move over the image
