hi,
may i know HOW to set the pixel value outside of the rectangular(ROI) as a constant value
and the pixel value inside the rectangular is the actual value of the image?
i try the convertROItomask.vi, it make the pixel value outside the rectangular to 0, but it also make the pixel value
inside the rectangular to a constant value as well..
and WHYwhile i using the convertROItomask.vi, some loop will produce non-zero value for the value outside of
the rectangular(ROI) during i play the avi file?
it should be zero value all the time during i play the avi file.
thank you
