Image Processing using the GPU
==============================

Disclaimer: This is a nVidia demo that has been modified.


Very Basic image processing using graphics hardware. It has been developed using Visual Studio 8 using a nVidia GeForce 6800 Ultra. 

There are different fragment shaders for performing one of Smoothing, Sobel edge detection, Laplacian edge detection with 3x3 and 5x5 kernel. 

Key choices: 

'b' = Mean Smoothing 
'e' = Edge detection using Sobel mask
'l' = Laplacian edge detection (3x3 kernel)
'k' = 5x5 Laplacian kernel for edge detection 

Its very basic as of now and any corrections/suggestions would be greatly appreciated. Please send them to me at alark1 AT cs.umbc.edu. 

The image resolution used is 512x512. It could easily be changed and would require very little tweaking.
