Manipulating pixels in a 3D array composed of stacked 2D arrays.

[iZACHdx]

Overview:  This VI simply adds together all pixel values and places them in a single resultant 2D array.

---

Description:

The first array is a 3d array of values. The second array is a resultant 2D array of values after performing an operation on all values in the z-direction for each element. Such an array might be a collection of 2D arrays stacked on top of each other such as a collection of images. Thus, x and y are the values in an individual image while z corresponds to the image number - literally a stack of images. If the user wanted to perform some sort of analysis on each pixel, they need a way to hold the pixel value constant (x, y) and step through the stack of images in the z-direction. Finally, the result is placed in a final array after all the elements have been analyzed. This VI simply adds together all pixel values and places them in a single resultant 2D array.

Requirements: LabVIEW 2012 (or compatible). Hardware: none.

---

Steps to Implement or Execute Code: Run the VI.

Additional Information or References: 

 

For demonstrational purposes, I simply chose to add together all the z-values for each pixel (x,y location). The loop containing this manipulation can be replaced with any other type of array operation or analysis.
