Hierarchical lossless coding of light fields with improved random access

作者：

Highlights：

• Light field lossless hierarchical codec with enhanced stream navigation.

• Scalability and random access navigation on the decoded sub-aperture images.

• Flexible selection of reference images for prediction with disparity compensation.

• Better performance than state-of-the-art in terms of bitrate and random access penalty.
