title: Fiber orientation measurement using polarization imaging.
abstract: In this paper, we present a new technique to determine the orientation of hair fiber, a key parameter in the evaluation of visual appearance of hair. Using polarization imaging and image analysis tools, we are able to measure the orientation of hair fiber for each pixel in the image. A theoretical analysis of the optical set-up is presented. Experimental data on a single fiber, hair tress, and complete head are given. Application to shampoo and conditioner is also demonstrated.
