This later approach can also be considered as a two-layer, base plus enhancement, encoding. This methodology can also be applied to V+D and MVD, where the enhancement layer is the depth information. Different strategies for advanced 3D video delivery over different content delivery path will be discussed in Chapters 8 and 10. Several 3D applications will be dealt with in Chapter 9. 5 3D Display To perceive a 3D scene by the human visual system (HVS), the display system is designed to present sufficient depth information for each object such that HVS can reconstruct each object's 3D positions.

For complicated scenes, the interactive 2D-to-3D conversion, or offline conversion, tends to be adopted, that is, human interaction is required at certain stages of the processing flow, which could be in object segmentation, object selection, object shape or depth adjustment, object occlusion order specification, and so on. In Chapter 4, a few 2D-to-3D conversation systems are showcased to give details of the whole process flow. 3 3D Video Compression Owing to the huge amount of 3D video data, there is a strong need to develop efficient 3D video compression methods.

The computation complexity via image based representation is proportional to the number of pixels in the reference and output images, but in general not to the geometric complexity such as triangle counts. However, the synthesis ability of image based representation has limitations on the range of view change and the quality depends on the scene depth variation, the resolution of each view, and the number of views. The challenge for this approach is that a tremendous amount of image data needs to be stored, transferred, and processed in order to achieve a good quality synthesized view, otherwise interpolation and occlusion artifacts will appear in the synthesized image due to lack of source data.
