Introduction to the Issue on Light Field Image Processing

Light field technology still suffers from crucial problems such as low spatial resolution, poor reconstructed depth quality, or large data storage requirements. Similarly, human interaction with four-dimensional data remains a challenging problem. Therefore, light field research is still in need of better theories and methods, targeting for more efficient data capture, analysis, processing, and storage. To this end, this special issue aims at providing readers with the latest developments and emerging technologies that aim to advance the field, and in the end make light fields more practical. For this purpose, 23 papers have been selected during the review process from 43 submissions. These are briefly summarized.
