Hair Color Digitization through Imaging and Deep Inverse Graphics. (arXiv:2202.03723v1 [cs.GR])

Hair appearance is a complex phenomenon due to hair geometry and how the
light bounces on different hair fibers. For this reason, reproducing a specific
hair color in a rendering environment is a challenging task that requires
manual work and expert knowledge in computer graphics to tune the result
visually. While current hair capture methods focus on hair shape estimation
many applications could benefit from an automated method for capturing the
appearance of a physical hair sample, from augmented/virtual reality …
