Hello,
I am receiving NaN results from the Colour JND Difference Calculator. I have read previous forum which stated the same problem and did what as suggested by rolling back my ImageJ version to 1.5. However, it still does not work and the JND is still NaN. May I know how can I resolve this problem?
Thank you!
Hi,
The main reason why there might be an NaN is if the cone catch is negative in one or more of the inputs. However, there are multiple reasons as to why there might be an NaN. I am not overly familiar with the JND difference calculator (it’s pre QCPA) and you might want to reach out to Jolyon with a detailed description of your issue and associated files needed to recreate the issue.
If you fail to get a response, please feel free to send me the same and I’ll see what I can do!
Cheers,
Cedric
