Abstract

Systems and methods are provided for using a Multi Focal Plane (MFP) prediction in predictive coding. The system detects a camera viewpoint change between a current frame from a current camera viewpoint to a previous frame from a previous camera viewpoint, decomposes a reconstructed previous frame to a plurality of focal planes, adjusts the plurality of focal planes from the previous camera viewpoint to correspond with the current camera viewpoint, generates an MFP prediction by summing pixel values of the adjusted plurality of focal planes along a plurality of optical axes from the current camera viewpoint, determines an MFP prediction error between the MFP prediction and the current frame, quantizes and codes the MFP prediction error, and transmits, to a receiver over a communication network, the camera viewpoint change and the coded quantized MFP prediction error for reconstruction of the current frame and display of the 3D scene.
