Este artigo examina os resultados de vários estudos sobre codificação de imagens 3-D. Os temas são focados na compactação eficiente e na representação independente de exibição de imagens 3D. A maioria dos trabalhos sobre codificação de imagens 3D concentrou-se nos métodos de compressão ajustados para cada um dos formatos de imagem 3D (pares estéreo, imagens multi-visualização, imagens volumétricas, hologramas e assim por diante). Para a compressão de imagens estéreo, foram desenvolvidas diversas técnicas preocupadas com o conceito de compensação de disparidades. Para a compressão de imagens multi-view, os conceitos de compensação de disparidade e imagem do plano epipolar (EPI) são as formas eficientes de explorar redundâncias entre múltiplas visualizações. Estas técnicas, no entanto, dependem fortemente das configurações limitadas da câmera. A fim de considerar de forma abrangente muitas outras configurações de múltiplas visualizações e outros tipos de imagens 3-D, é introduzida uma plataforma mais geral para a representação de imagens 3-D, com o objetivo de superar a estrutura da comunicação de "imagem" 3-D e abrir um novo campo da tecnologia, que deveria ser chamado de comunicação "espacial". Especialmente, o método baseado em raios de luz tem uma ampla gama de aplicações, incluindo transmissão eficiente do mundo físico, bem como integração dos mundos virtual e físico.

Abstract: This paper surveys the results of various studies on 3-D image coding. Themes are focused on efficient compression and display-independent representation of 3-D images. Most of the works on 3-D image coding have been concentrated on the compression methods tuned for each of the 3-D image formats (stereo pairs, multi-view images, volumetric images, holograms and so on). For the compression of stereo images, several techniques concerned with the concept of disparity compensation have been developed. For the compression of multi-view images, the concepts of disparity compensation and epipolar plane image (EPI) are the efficient ways of exploiting redundancies between multiple views. These techniques, however, heavily depend on the limited camera configurations. In order to consider many other multi-view configurations and other types of 3-D images comprehensively, more general platform for the 3-D image representation is introduced, aiming to outgrow the framework of 3-D "image" communication and to open up a novel field of technology, which should be called the "spatial" communication. Especially, the light ray based method has a wide range of application, including efficient transmission of the physical world, as well as integration of the virtual and physical worlds.
