Hi! I use Gunpowder for H&E pathology images, which often suffer from inconsistent staining and illumination. These are typically three-channel images, where channels are (R, G, B); or (Hematoxylin, Eosin, Residual). I augmented the images with gunpowder.IntensityAugment() to avoid overfitting on this inconsistent staining.
However, to my knowledge, gunpowder.IntensityAugment only changes the overall intensity of a patch.
It would be amazing if it were possible to change the intensity of the individual channels, i.e., the color of a patch. This would also benefit other types of multi-channel images, such as fluorescence microscopy images. Ideally, controlling the amount of change in each channel should be possible.
Thank you!
