Basic Image Processing (without MATLAB built-in Functions)

The code uses basic image processing methods to compute histogram of an image and perform equalization for better dynamic range of image.

The code is simple enough to understand.
The basic processes (without using the built-in functions) in the code are as under:-
a. RGB to Gray conversion.
b. Histogram computation.
c. Gray Level Degradation/Compression (Image Darkening or Image Brightening)
d. Contrast Stretching
e. Histogram Equalization.
