... surface gradients and the albedo and also perform blind image restoration. The surface gradients and the albedo are modeled as separate Markov random fields (MRFs), and a suitable regularization ... used for the same, and graph cuts were used for optimization. The advantage of the proposed approach is that we obtain the light source position, scene structure,...

... speed and steady-state performance. Note also that regularization is usually unnecessary in (21) and (24) for adequate values of ν. (Regularization would be implemented in (21 )and( 24) by using a ... each sensor must know the locations of the other sensors. This unfortunately imposes a substantial demand for both storage and computational time, as most practical applica...
