How this Error occur in LOMO implementation?

when i comment this 'I = Retinex(I);' in LOMO>PyramidMaxJointHist (line 120) the output comes, but i think this line also useful functionality that why developer of that add it, so how can i run this descriptor without commenting this line. i am waiting for helpful comment on it, thanks

This appears to relate to https://github.com/neelabhro/Multi-view-semantic-projection-learning-for-PRID

As no function named LOMO is defined, it looks like LOMO must be the name of a variable loaded from a .mat file. I do not seem to be motivated to download the .mat and go looking for it. Especially as it looks as if it must be a function handle to something...
