Hello, now I can get one ROI on screen & get the histogram
However I want to analyze several ROIs at the same time, how should I deal with it?
I googled about multiple ROIs ,and it seems that I should use UNGROUP ROIs
but the connection is incorrect... how to fix it?
and after ungroup the ROIs, can I get the histogram mean value from each ROI?
Thanks for any advices.
-The Ungroup ROIs output is an array of ROI descriptors.
-Which means you have to index each ROI descriptor and apply to image by using for loop.
