Optimizations done
--------------------

1. Made Iterative FFT
2. Minimized Paramter Passing esp. copying of arrays

3. Use of Inline functions
4. Bit shifting used - Optimized math operations
5. Recomputation of FFT avoided for each filter - use copy
6. For Ideal High Pass optimization done

--Spatial

1. LOCAL HISTOGRAM EQUAL  WINDOW MOVING
 

Features
--------------
1. Inbuilt timers
2. Menu driven program
3. Save option at each step
4. Automatic centering of FFT done
5. Includes Image Magick functions for Equalization and Median Filter.

Concepts
----------

*  Explanation ringing effect.
*  Butterworth approaches high pass
