Abstract
A method and an apparatus for data retrieval in a lightfield database are described. An acquiring unit of the apparatus acquires a sample data. An operation unit determines a plurality of two-dimensional (2D) images from each 4D lightfield data of the lightfield database, and match the sample data with the determined 2D images according to geometrical parameters of the sample data and geometrical parameters of the 2D images. One of the 2D images is selected as a target image based on the matching result, and the 4D lightfield from which the target image is determined is retrieved.
