Even though shadows are important for photometric consistency in Mixed Reality (MR) [1]. When human cannot perceive the inconsistency of artificial shadows which are not physically correct, they are acceptable as " perceptually-correct " shadows. This paper focuses on the simplification of light source models for generating the perceptually-correct(More)
Crack development in concrete structures starts at the micro-crack stage and proceeds to the macro-crack stage due to repeated cyclic loading, like ongoing vehicles on bridges. Automatic detection of early stage cracks is required for both safety and economic reasons. We present an automatic crack detection method that scans a captured concrete area and(More)
