Compensation of illumination radiance in photometric stereo (2010)
Presentation / Conference
Sun, J. (2010, December). Compensation of illumination radiance in photometric stereo. Paper presented at 2010 IEEE The 3rd International Conference on Machine Vision

This paper presents a new strategy to counter camouflage by capturing (one more) additional images of same scene. The strategy is based on a technique we call 'two-light photometric stereo', which can remove disruptive reflectance from luminance imag...
