Hi ,

         I need to find the circle find using circular edge detection. here i need to change my ROI . so i have used Property Node of Image display.  

           But i cannot change my ROI. 

         I have attached my VI file

-Please check this for Defining ROI in interactive or programmatic way http://zone.ni.com/reference/en-XX/help/370281P-01/nivisionlvbasics/define_regions_of_interest/#Defi...
-What do you mean by change ROI? in your program now, whatever roi has been drawn or selected in the image indicator will be given when taken ROI property node of the image indicator.

I understand you want to change your ROI...did you check the link which i provided in earlier post?
-Changing ROI means giving different co-ordinates, how you are giving them?
-simply selecting the property ROI will give nothing unless you draw something in the image indicator. So, when you select ROI tool and draw something then the ROI parameters will be passed to property node.

Hello,

you need to use "Annulus Tool" to create a ROI for circular edge detection (either programmatically or manually).
