Enquire the RGB images

[htritapeng]

Hi Muhammed,
Thanks for your paper. It inspires me to develop a research topic on transfer learning of Chest X-rays related to COVID-19.

Since the data you use in this paper are quite suitable for my research, I would like to use the images you collected here. However, transfer learning needs RGB images to be compatible with the pre-trained weight, but some images of your dataset are grey. So I was wondering if you have those images in the RGB version, or would you have any suggestions for me to do image processing?

It would be appreciated if I could have your suggestions.
