Abstract:
A method for encoding at least one matrix of image views obtained from data acquired by a plenoptic camera is disclosed. Image views of the matrix of image views are partitioned into blocks. For a given image view of the at least one matrix of views, the method includes obtaining at least one block to be encoded and a matching block, wherein a difference between the at least one block to be encoded and the matching block fulfills a block matching criterion; determining a residual block regarding the at least one block to be encoded and the matching block, the determining using modified pixels of the at least one block to be encoded and modified pixels of the matching block according to flux variation parameters associated with a pixel sensor of the plenoptic camera; and encoding the residual block.
