This paper investigates the problem of extracting 3D shape from flat 2D images. In contrast with conventional methods, this work uses two images captured from the same position but under different illuminations to reconstruct a 3D shape. The proposed novel algorithm is based on an underdetermined system by seeking sparseness and statistical independence between direct illumination and object shape within a statistical estimation framework. The technology proposed surpasses the minimum… CONTINUE READING
