** normalization schedule:
1. # Integer to float conversion - Converts 256 gray levels into floating point equivalents.2. # Geometric normalization – Lines up human chosen eye coordinates.3. # Masking – Crops the image using an elliptical mask and image borders such that only the face from
forehead to chin and cheek to cheek is visible.
4. # Histogram equalization – Equalizes the histogram of the unmasked part of the image.5. # Pixel normalization – scales the pixel values to have a mean of zero and a standard deviation of one.
