JND every photo receives under 1 values

Hi,

I ran the following steps:

1. generate multispectral image from a linearized JPEG
2. covert to cone catch (humans)
3. run Batch Multispectral Image Analysis
4. Colour JND difference calculator (animal and background ROI)

While everything runs without error, I noticed a few odd results:

• coverage of the luminance results are all zero
• all the results from batch are very low under 1.0
• all the JND are under 1.0.

Anything would help! thank you very much for this great tools in image analysis!

Best
