Background:

Accurate segmentation of 4D light fields is crucial but challenging due to data volume and redundancy.
Existing methods struggle with the complexity of light field data.

Purpose of the Study:

To propose a novel light field hypergraph (LFHG) representation for interactive light field segmentation.
To enhance segmentation accuracy and efficiency using light field super-pixels (LFSPs).

Main Methods:

Introduced a light field hypergraph (LFHG) representation leveraging light field super-pixels (LFSPs).
LFSPs preserve spatio-angular consistency and facilitate hypergraph coarsening.
Developed an efficient segmentation algorithm based on LFHG and graph-cut optimization.

Main Results:

The proposed LFSP-based LFHG representation significantly improves segmentation performance.
Experimental results show superior accuracy and efficiency compared to state-of-the-art methods.
Validated on both synthetic and real-world light field datasets.

Conclusions:

The novel LFHG representation with LFSPs offers an effective solution for 4D light field segmentation.
The method achieves state-of-the-art results in accuracy and efficiency.
This approach advances interactive light field segmentation capabilities.
