Hi! I really enjoyed reading your paper and would like to work with your RAW dataset.

I see the low resolution images are 4 channels, but why is the high resolution raw image 3 channels? What processing has occurred to the high resolution raw images?

In https://github.com/yjsunnn/FBANet/issues/10#issuecomment-1871798894, you shared a Baidu link with some utils and scripts. Would you be able to upload them to google drive? I'm unfortunately unable to create a Baidu account.

Thanks!

  1. LR image to HR image need demosaic which covert ch3 to ch4. you can search "demosic process" for more technology detail.
  2. this is all your need that occured in issue 10 and issuce 11

Thank you for sharing the raw zip!

Sorry I am confused by what you mean in 1. Shouldn't the HR RAW also be 4 channels if the LR RAW is 4 channels? Or are you saying that in the HR RAW, you already demosaiced the 4 channels into a 3 channel format by a standard demosaic-ing algorithm? Is this demoniac-ing the only correction or is there also denoising/gamma correction etc? Thanks so much!
