How to Reduce Noise
–
•For a pixel in image I at I,j
•
•
•
•
•Computing this for every pixel location is the convolution of the image I with the template (or kernel) consisting of a 3x3 array of 1’s.
•
•Note that is this O(n2m2) for an nxn image and mxm template.
•
•Note we have to normalize the template to 1 to make sure we don’t introduce any scaling into the image.
