| Abstract: |
This paper introduces a new theoretical model on the rate-distortion performance in transmitting multi-view image data. To reduce the data amount, a practical solution is just decreasing the number of images by subsampling. The questions we focus on are (i) how much bit-rate can be reduced, and (ii) how much additional distortion would be caused, by the subsampling of images. In our theoretical model, the rate-distortion theory and the plenoptic sampling theory are combined to consider the relation between the sampling condition (the cameras' interval) and the compression efficiency. Numerical simulations which show the theoretical lower bounds for (i) and (ii) are presented with discussions. |
