|Abstract:||The light field cameras are becoming a new trend in photography. They have characteristics that could overcome some problems present in surveillance videos, like refocusing and depth estimation. The main advantage is that the light field camera allows focus reconstruction, increasing the depth of field. However, these new cameras require different processing power and storage than conventional cameras. In this paper, it is shown how these cameras work and how they could be employed in surveillance. Images of a standard surveillance camera versus the plenoptic camera are compared and some issues about the design of the light field camera are discussed. Finally, we compare the performance of video compression standards applied to plenoptic image sequences. The power signal noise ratio results show that MPEG4 is the best choice|
