How to find the pixel location of each blob in labelled image more efficiently ?

[marxious]

I've been using the vision development tool for a while now, what I feel is lacking is that reporting of blob location after the operation IMAQ label.vi

An inefficient way to locate each blob location is to use IMAQ threshold, and basically iterate through all blob labelled value to get each non-zero get pixel locations.

However, this method is pain when there's a lot of blobs and also I feel this is so inefficient. Since IMAQ quantify seems to be able to compute the region statistic on blob image, the roi must have been saved some where. Can anyone provide some insight to perform this in a more efficient way ?

You can use IMAQ Particle Analysis(http://zone.ni.com/reference/en-XX/help/370281M-01/imaqvision/imaq_particle_analysis/) to get the ROI of each Particle in array and many more measurements which you can select.
