			profileWidth,
			debug )

calculate image intensity profile for line ROI based on code by Damien in comments of http://se.mathworks.com/matlabcentral/fileexchange/11568-extract-integrated-intensity-profiles-from-image

Parameters

img	an image to be used for intensity calculations ([height, width, colors])
x1	x1 coordinate for the line
y1	y1 coordinate for the line
x2	x2 coordinate for the line
y2	y2 coordinate for the line
profileWidth	a number that defines the width of the intensity profile
debug	[optional] - a switch to show debug plots

Return values

ProfileOut	matrix with intensity profiles for all color channels [colChannel, 1:points]
profileLength	length of the intensity profile in pixels
samplePntsX	x coordinates of the X sample points as (widthIndex, Xcoordinate]
samplePntsY	y coordinates of the Y sample points as (widthIndex, Ycoordinate]
