  Efficient and accurate segmentation of light field is an important task in
computer vision and graphics. The large volume of input data and the redundancy
of light field make it an open challenge. In the paper, we propose a novel
graph representation for interactive light field segmentation based on light
field super-pixel (LFSP). The LFSP not only maintains light field redundancy,
but also greatly reduces the graph size. These advantages make LFSP useful to
improve segmentation efficiency. Based on LFSP graph structure, we present an
efficient light field segmentation algorithm using graph-cuts. Experimental
results on both synthetic and real dataset demonstrate that our method is
superior to previous light field segmentation algorithms with respect to
accuracy and efficiency.
