Abstract
Edit propagation algorithms are a powerful tool for performing complex edits with a few coarse strokes. However, current methods fail when dealing with light fields, since these methods do not account for view-consistency and due to the large size of data that needs to be handled. In this work we propose a new scalable algorithm for light field edit propagation, based on reparametrizing the input light field so that the coherence in the angular domain of the edits is preserved. Then, we handle the large size and dimensionality of the light field by using a downsampling-upsampling approach, where the edits are propagated in a reduced version of the light field, and then upsampled to the original resolution. We demonstrate that our method improves angular consistency in several experimental results.

We can represent the light field as a 2D matrix composed of the different views, as per common practice.
