Summary on Grant Application Form
The proposed research is set in the context of the convergence between graphics and image processing research. In particular, the emergence of light field methods for photo-realistic graphics has led to the development of compression algorithms to deal with the high data volumes it generates. More generally, in recent years, there has been considerable interest in the use of multiple cameras to enhance the experience of viewers of broadcast television, and enhanced or virtual reality systems. However, this raises the problem of how to compress the resulting large data volumes for efficient storage and transmission.Existing compression methods tend to use disparity compensation, a form of predictive coding analogous to motion compensation. Due to its inability to deal properly with occlusions unless an explicit object model is provided, disparity compensation is not hugely successful in terms of compression, nor does it provide automatic interpolation of views from arbitrary points in the space. Moreover, since the existing algorithms for interpolation are somewhat ad hoc, a large number of images, having high overlap, is required.The proposed research aims to develop an appropriate representation, which will result in efficient compression algorithms and from which it will be possible to change the viewing point at will, at low cost in decoding time.
