Evolution of stereoscopic and three-dimensional video

An improved, wavelet-based, stereoscopic image sequence codec with SNR and spatial scalability

“…This is achieved by estimating disparity vectors. Due to its simplicity and demonstrated use with hardware for encoding stereoscopic imagery [33], we propose using a 3-scale, hierarchical block-based disparity estimation scheme. The hierarchical nature of a 2D separable DWT insures that no additional downsampling is required in order to obtain lower spatial-resolution versions of both reference and target images.…”

“…The authors in [5] use a non-embedded wavelet-based scheme for encoding stereoscopic moving images. A hierarchical, blockbased, disparity-and motion-compensated prediction scheme [27,33] is used. The scheme in [5] is computationally less intensive than the one presented in [25] but, results from the latter algorithm are superior when compared with the former algorithm.…”

PDE Based Surface Estimation for Structure from Motion

“…The estimation of surface models from multiple images, the so-called multiple view stereo problem, is one of the classical problems within computer vision (e.g. [4,8,10,16]). Some of the best results are achieved by Faugeras and Keriven by posing the problem as a partial differential equation PDE [2,3,4], this has been further developed in [7].…”

“…Some of the merits of this approach are, that it in a naturally way employs all the images simultaneously as opposed to the adapted 2 image stereo approaches (e.g. [10,16]) and that it is capable of dealing with objects of arbitrary topology.…”
