Filters Category
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
