Abstract(in English) The human visual system (HVS) has more sensitive spatial resolution to the currently gazing region-of-interest (ROI) of the scene, and the sensitivity becomes decreased to the peripheral regions. This intro- duces considerable perceptual redundancy in low-interest regions. Considering this redundancy of human visual perception, in this paper, we discuss a fundamental approach for traffic reduction on crowdsourced multi-view video uploading. For this purpose, we extend our previously proposed differential encoding-based video uploading scheme using ROI-based multi-view video encoding. To realize the ROI-based differential multi-view video uploading, we first construct a correlated network of contributors based on their correlation degrees. We then select a contributor with the largest average correlation in the network for extraction of ROI regions. The selected contributor uploads its video stream using ROI-based single-view video encoding while the rest of the contributors in the network over- hear the transmitted stream and performs ROI-based differential multi-view video encoding with the prior ROI information. Evaluation results show that our approach achieves 57% of traffic reduction under the same visual quality in ROI regions and unnoticeable visual degradation in low-interest regions.
