Dialog box for input of data sampling and weights for red, green
and blue signals for luminance calculation for SFR calculation
Usage: [del, weights] = inbox3(def_del, def_weights)
def_del = (optional) default sampling interval in mm or dpi
if not used, def_del = 1
def_weights = (optional) default 3x1 array of luminance weights for R, G, B
if not used, def_weights = [0.3 0.6 0.1]
del = output sampling interval in mm
weights = output 3x1 array of luminance weights for R, G, B
Calls inputdlg function, supplied with the toolbox
matlab/uitools. If you have problems, check which version of
inputdlg.m (or corresponding inputdlg.p) is being called. You need
version 1.48 or later.
