Abstract
Predicting a component of a current pixel belonging to a current sub-aperture image in a matrix of sub-aperture images captured by a sensor of a type I plenoptic camera can involve, first, determining a location on the sensor based on: a distance from an exit pupil of a main lens of the camera to a micro-lens array of the camera; a focal length of the main lens; a focal length of the micro-lenses of the micro-lens array; and a set of parameters of a model of the camera allowing for a derivation of a two-plane parameterization describing the field of rays corresponding to the pixels of the sensor; and, second, predicting the component based on one reference pixel belonging to a reference sub-aperture image in the matrix and located on the sensor in a neighborhood of the location.
