Description
After a stem cell transplant, donor immune cells can attack the patient's skin, a condition called chronic graft-versus-host disease. Judging its redness by eye is unreliable, and darkened skin confuses the estimate further. Mayaank Pillai and co-authors present a 2026 method that separates the two changes from ordinary color photographs.
Their pipeline first rebuilds a richer light spectrum from the photo, then unmixes it into maps of blood pigment and skin pigment. Those maps stand in for redness and darkening. The method learned only from synthetic images, yet it classified both conditions with median accuracy above 0.70 on test images and real clinical photos. The authors offer it as a cheaper stand-in for costly hyperspectral cameras.
