We present an algorithm for separating the local gradient information and Lambertian color by using 4-source color photometric stereo in the presence of highlights and shadows. [...] Key Method The conventional photometric method is generalized for color images. Shadows and highlights in the input images are detected using either spectral or directional cues and excluded from the recovery process, thus giving more reliable estimates of local surface parameters.Expand

TLDR
This reconstruction method is able to identify areas where the majority of the lighting directions result in unreliable pixel intensities, providing the capability to adjust a reconstruction algorithm and improve its performance avoiding the unreliable sources. Expand
Generalisation of Photometric Stereo technique to Q-illuminants
We present a generalisation of the 4-light photometric stereo technique to an arbitrary number Q of illuminants. We assume that the surface reflectance can be approximated by the Lambertian modelExpand
Photometric stereo with an arbitrary number of illuminants
TLDR
The algorithm works in a recursive manner eliminating the pixel intensities affected by shadows or highlights, based on a least squares error technique, retaining only the information coming from illumination directions that can be used for photometric stereo reconstruction of the normal of the corresponding surface patch.
