Wow! If you wrote this code, I recommend finding someone who is an expert at Image Analysis and knows what GLCM (I bet you spell LabVIEW wrong, as well) is and means. If you want them to code in LabVIEW, ask to see a sample of their code -- if they use any sequence structures, or if no Block Diagram fits on a single screen, reject them and keep looking.
You do know, I presume, that the "G" stands for "Grey" (or "Gray"), and you know you are reading in images in Grayscale. So why are there functions "Color to RGB" in this VI? If you want to develop an algorithm whose first name is "Gray" (or "Grey"), why don't you forget all about "colorizing" your Image and implement the algorithm? The method is pretty straight-forward -- just follow the instructions. When in doubt, take a constant Image and analyze it. When you've done that, and have a simple VI that takes a given grayscale image (which you've attached) and implements your attempt at the GLCM algorithm, attach the Image and the Algorithm if you are still having problems and we'll critique your code. But focus on the GLCM.
