| Résumé : | Light and vision are two sides of a coin playing a major role in everyday human life. Over the years, visual related technologies, notably acquisition, representation, coding, transmission, storage, and display have evolved to offer an increasingly large set of functionalities, applications, and services. With the invasion of the digital paradigm, the speed of this evolution has only increased, still mostly based on the so-called (2D) frame-based model, consistently used from the acquisition to the display. More recently, new cameras and displays have been emerging exploiting richer representations of the scene light, notably acquiring, processing, and displaying not only light at certain positions but also light with certain directions. This emerging richer light representation models reopened the fundamental discussion of light representation, processing, and coding, many times made under the umbrella of the so-called plenoptic function. This chapter will review and discuss the basics and recent developments related to visual acquisition, representation, and display from a plenoptic function perspective, notably plenoptic imaging representation and processing with particular emphasis on coding and rendering. |
