Analytical model of multiview autostereoscopic 3D display with a barrier or a lenticular plate

Abstract

A geometric model of an autostereoscopic 3D display is described herein. This model is based on the geometry of typical display devices and on the projective transformations that provide periodicity in the projective space. The formulas for the transformations between regions and spaces are provided. The model can be applied to the study of an operation of the multiview, integral, plenoptic, and lightfield displays. A practical application considered in this paper is the multiview wavelet transform. ARTICLE HISTORY

Depth Analysis of Greyscale Integral Images Using Continuous Multiview Wavelet Transform

“…The result of the wavelet analysis of 3D images, however, depends on the colour/texture of the surface of the object. This effect was noticed before, and the most images in [9][10][11] were binary BW images and most results were presented in a qualitative visual form. This unexpected undesirable effect must be reduced, but a solution has been unknown yet.…”

“…The multiview wavelets and the algorithm of the continuous multiview wavelet transform are exactly the same as presented in our previous paper about the multiview wavelets [10,11].…”

“…Particularly, the wavelets are used in 3D imaging, for instance, in multiview video compression [4], in image coding [5], in image fusion [6], as a quality metric [7], etc. The disparity of stereoscopic images can be estimated [8], the shape of the photographed/synthesized objects can be analysed, and the depth can be extracted using the wavelet analysis of the integral images [9][10][11]. In this paper, we propose the technique to eliminate the texture effect.…”
