In this paper, we propose a fast method for separating reflection components using a single color image. We first propose a specular-free two-band image that is a specularity-inva...
The reflection theorem has been proved using Isabelle/ZF. This theorem cannot be expressed in ZF, and its proof requires reasoning at the meta-level. There is a particularly elegan...
We define a bijection that transforms an alternating sign matrix A with one -1 into a pair (N, E) where N is a (so called) neutral alternating sign matrix (with one -1) and E is an...
In Photometric stereo, the existence of specularities hampers to recover the normal map. To deal with this common reflective phenomenon, we introduce a novel representation for spe...
