Hi orobix,

First thanks for sharing your work :) but I have some questions :

1) Can all your data pre-processing steps be used channel-wise with rgb data ? or some transformations shouldn't ? (gamma ?)

2) How did you find the value for the gamma correction for example, did you try with you eyes ? with your model ? is it a standard (for this dataset only ?) ?

3) Why you transform your data to grayscale ? Aren't you loosing information ? Is there any specific reasons ? which ones ?

Did you end up finding answers to any of these questions?
