Hello,
I´d like to write a function for calculating delta E as a color difference measure between images. I want to make it work with images in RGB space and LAB-Space. Therefore I need to check in which color represenation the input images are given. How can I do this?
Regards, Daniel

See the delta E demo in my File Exchange: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862
For a 3D array of numbers, there's no way to tell if that represents any particular color space. You have to know in advance from knowing what file you read in and what it represents, and what you did to it afterwards (like if you converted it to a different color space).

Hi,
thank you for your answer. I will have to think about a different solution for managing images in different colorspaces.
