find histogram using mask image having multiple blobs

[aveo]

HI All,

I want to find out the histogram of some selected regions in an image. These selected regions are present in a binary image(mask image). 

Now I want to get the histogram of each region. How can this be done in a quick way? 

What I can think of is converting the mask image into a labelled image and then use a for loop to threshold out each particle and then use imaq histogram to find the histogram of each particle. 

Is there any better/faster way?

Thank You,

Regards

Sounds like an excellent job for a custom C++ blob analysis VI that accumulates histograms as it scans for blobs in the image.

Have fun!
