This tool is able to separately record individual properties of hair shine such as specular reflection and multiple reflection, as well as additional features such as sparkle, parallelism of hair fibers, and hair color, which strongly affect the subjective(More)
This paper introduces a method for evaluation of the contrast of a moving lattice (grille) pattern without imaging data acquisition and image analysis. We characterize the dynamic performance of the display under test in terms of the periodic impulse response followed by evaluation of the contrast of the corresponding test-pattern in motion. It thus becomes(More)
