Labview Image processing

[arunamv12]

Hi,.

I need to extract region of interest and intensity plot from an image. I am attaching my algorithm and labview program below. Please help me to do that...

Here are some comments:

• The part of your code where you extract the Image looks (more or less) OK.  The problem is your implementation of the algorithm shown in the attachment.
• The Gxx and Gyy matrices are Controls, so their values are not "fixed".  I would make them Constants, and put the values ((0,0,0), (-1,2,-1), (0,0,0)) for Gxx, for example) in them.
• You skip part of Step 4 -- you don't take Absolute Values.
• I don't understand "Take the average of the sum matrix twice", unless it means "Average the rows to make a 1D vector, then average the Vector".  You almost do this -- the Sigma function adds up all the elements, but the Array Size function needs a Product (Pi) function to multiply the number of rows times the number of columns = number of 2D array elements.
