Multispectral imaging and photometric stereo are common in 3D imaging but rarely have been combined. Reconstructing a 3D object's shape using photometric stereo is challenging owing to indirect illumination, specular reflection, and self-shadows, and removing interreflection in photometric stereo is problematic. A new multispectral photometric-stereo method(More)
Measuring and quantifying color defects in flat panel displays (FPDs) are critical in the FPD industry and related business. Color defects are traditionally investigated by professional human assessors as color defects are subtle perceptual phenomena that are difficult to detect using a camera system. However, human-based inspection has hindered the(More)
