I have two groups of image,first group contains clear edges,and the second group doesn't have clear edges ,and I have two segmentation algorithms for each Images group so what I want to do:

1-If the image contains edge use the first segmentation algorithm

2-Else run the second segmentation algorithm,How can I do this procedure depending on the value of deltaE? (please find attached file for main_function,LocalDeltaE) this first sample image below

has clear edges,so I'll use the first segmentation algorithm(I have it's code),where the second image below has no clear edges so I'll the second segmentation algorithm

clear edges image is below

non-clear edges image is below

and the codes which I tried (depending on Image Analyst LocalDeltaE function ) are attached here[decision_value] = LocalDeltaE();

That's a very slowly varying, smooth image. Chances are you didn't use a large enough window. Using 5 like in the demo is only good for fairly sharp edges. You might need 31 or 51 or something.
