Analysis of Depth in Integral, Multiview and Plenoptic Images by Using Multiview Wavelets

Abstract
The wavelet analysis of the integral images can be applied to extract the depth from the photographed/synthesized 3D objects. Multiview wavelets can be based either on the Haar wavelets or on the B-splines. The continuous wavelet transform was applied to the testing wireframe binary objects. The restored locations correspond to the structure of the testing wireframe binary objects. The result of the wavelet analysis, however, depends on the colour/texture of the object, and thus can be ambiguous. In order to avoid such an ambiguity, the normalization of the image before processing was proposed, so as the extraction of the depth could be performed with no regards to the colour/texture. The improved technique was verified in multiple integral/plenoptic images; it can be also applied to multiview and light field displays.
