Convertir les contours d'une image en tableau

[marmotte]

Hello,

I begin in Labview and its Vision module.
I have at present the outline of an image obtained with IMAQ Edge Detection whom I copied in tabular form exploitable under Excel for example.
The problem is we obtain a board (of dimension equal to the size of the image) where the values of cells correspond to the value of pixels.

I would want to know how to modify this board to have simply the coordinates of the points where I have a value superior to a threshold which would be grouped in a board of two columns. 

Thank you for your help

Hello Marmotte,

Has your problem been solved yet? Could it be possible to post it on the French forum? It would be easier for us to understand each other in French!

Have a nice day,

Hello, 

What you can do is use the "Threshold detector.vi"  function. It will output the indices of the elements that exeed the threshold for a 1D array you just need to add a for loop to make it work with 2D array.

Best regards,

FYI you should use array instead of board.
