How do I make MATLAB to recognize the deltaE function?
7 views (last 30 days)
I have two images A and B. When running the code that I am using to find colour differences between two images, it keeps telling me: "Unrecognized function or variable 'deltaE'. I tried to read about how to make this function recognized and I believe I have to convert the RGB images into lab values. Yet I keep failing to understand how to do so.

deltaE() function is available in Image processing toolbox. This error message indicates that, most likely, you don't have that toolbox installed. You can run the following line in the command window
and if you get a warning, it means that you don't have the toolbox installed.
