How do I get the infomation of points of a particle from using binary process function?

[48105]

Hi,

   I want to overlay a closed contour on the perimeter of the particle found by the function " imaqMeasureParticle." I need to have the information of the points in the perimeter of the particular particle for using the function "imaqOverlayClosedContour." I try to find a function for me to collect the information of points for me because you can find out the perimeter of the particle by the function " imaqMeasureParticle." So, I am supposed that there were a function to get the points info to calculate the perimeter. However, I cannot find it. Thus, I want to know that if there is any function I can use directly. Thank you in advance.

If I understand your problem, I can explain how I did nearly the same:

If you have a binary image than you can use the function mask to ROI, than ROI Profile and than you get the contour points of that ROI, e.g. a circle or ellipse. The problem is the origin image, you will need a really binary image and I mean an image with zeros and ones, not the Labview Binary Image! I used the treshold function to get that "really binary" image, it cuts off every pixel under / over a specified intensity and results an image where everything pixel is set to 1 which is greater (smaller) than the threshold and the rest to zero. Nothing else.
 If you have another solution, please tell.
