Neural Radiance Fields (NeRF) is a recent technology which had a large impact in computer vision, promising to generate high quality novel views and corresponding disparity map, all using a fairly small number of input images. In effect, they are a new way to represent a light field. In this paper, we compare NeRF with traditional light field metho...

Light fields are typically defined by two reference planes, between which rays can be described by their intersections with the planes. Throughout the literature on lenslet-based light field cameras, the reference planes are assumed to be the plane of the lenslet array and the plane of the imaging lens when modeled as a thin lens. Some works descri...

In this work we explore methods for allowing advanced colour editing on light field images to be performed. This investigation is twofold. First we look at soft colour algorithms to decompose images into colour layers and the various ways it could be applied to light field data in order to ensure spatially consistent results. Then, with the purpose...

Light field technology has reached a certain level of maturity in recent years, and its applications in both computer vision research and industry are offering new perspectives for cinematography and virtual reality. Several methods of capture exist, each with its own advantages and drawbacks. One of these methods involves the use of handheld pleno...

In recent years, light fields have become a major research topic and their applications span across the entire spectrum of classical image processing. Among the different methods used to capture a light field are the lenslet cameras, such as those developed by Lytro. While these cameras give a lot of freedom to the user, they also create light fiel...
