I Need on how to get x,y grey level values after IMAQ Count Object

Go to solution


  I need help.

  I have include two drawing.  a. IMAQ Count Object detect 4 objects.  b. 7x7 matrix drawing

  In my drawing (white dot is the brightest), (black is the darkest) and (Red dot is the center) of detect object.


  I need to get 2 info from the detect object.

1.  Need to have (X,Y) location value of the (darkest/brightest pixel) in each detect object.

     I have a grey scale picture and use the IMAQ Count Object, I am able to get the object.

     IMAQ Count Object return the "Center of mass of the binary object detected" X,Y value.

     But, I need the X,Y value of the darkest and brightest pixel location (in one object area) in turn of (x,y).

     (for my drawing example, I will get 4 set of data.  each set of data returns drakest and brightest X,Y location)

2.  Return the grey level of darkest/brightest object in 7x7. (darkest and brightest will be in the center of matrix)

     I need to provide the grey level in 7x7 matrix.  the darkest or the brightest will be place at the center of matrix.


Thank you for your help.

You can mask each particle, convert the image into an array and use the Array Min and Max VI to find the positions of the extrema.

Hello p4keal:

  Thank you. 

  I will search and see how to use mask module and try the method you mention.


  Also, I am new to LabView, do LabView have any module that I can use for 7x7 or nxn matrix? (I need to get the value surround the Brightest and darkest point on detect objects)


Thank you.
