IMAQ VI to measure intensity of an image

[Brendan crowley]

hey,
what im doing is subtracting to images, one is a mask of an empty conveyor belt, the other is one of a conveyor with a material stream on it, im trying to find the volume of the maerial in the second image.when th subtraction is done im left with a black background and a bright area representing tehe material. what is the est imaq VI to intensity of this bright area?
Cheers.

Brendan, can you then threshold the image and then use partical analysis/blob analysis to measure the area/volume?

You may have to invert the image first though?


Kind Regards
