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