/*
	Compile with opencv 2.1 April 2010 Release

	Assuming you have the libraries installed centrally, e.g. prefix /usr thus /usr/include and /usr/lib
	you can compile with:

	gcc -g -std=c99 -lopencv_highgui -lopencv_core -lopencv_imgproc -lopencv_features2d main.c -o CamTest

	I recommend -g so you can use gdb with something like gdb ./CamTest and then inside gdb:

	b 7
	run
