RGB to Black and White

22 Nov 2005 (Updated 07 Aug 2008)

Converts RGB images to black and white images

File Information
Description	This code converts an RGB image to a black and white image in C with MEX. I this together for a school project and I couldn't find any good examples of MEX with image processing. One note the code is currently hard coded to handle only UINT8, however it should be trivial to convert that data type. Enjoy.
MATLAB release	MATLAB 7.1.0 (R14SP3)
Other requirements	I built this under Windows with VC 2003 & R14SP3, but there is nothing platform or compiler specific about it.

08 Nov 2007	Matt -	This isn't RGB to black and white, it's RGB to gray scale.
06 Aug 2008	Anthony Gabrielson	Your right it did just handle grayscale. I threw in a function so it can take the grayscale image and convert it to a black & white.
