A learnable transformer decoder for blurred near-infrared blood vessel segmentation using domain adaptation with limited data

Jiazhe Wang, Yuya Ieiri, Osamu Yoshie, Koïchi Shimizu

Transillumination imaging using near-infrared (NIR) light is an effective method for visualizing subcutaneous blood vessels. However, as the vessel depth increases, images become severely blurred due to strong light scattering in body tissue. Although deep learning has shown great promise in clear …
