How do I compare my RGB images to identify the differences between them using Vision Assistant?


  1. From Vision Assistant, first use Get Image to select the source image (Image 1) you wish to compare. 
  2. Use Image Buffer to store the image into a buffer for comparison later.
  3. Use Get Image again to select the second image (Image 2) to compare with.
  4. Use Color Operator with Not Exclusive Or operation to show the differences between Image 1 and Image 2.


You may play around with other operation to obtain the result that is best representing your application.
