Abstract: Encoding a two depth images of points of a bounded volume (730); determining a first section across a second axis between the depth images to generate a feasible occupancy image and a list of pixels with unknown occupancy status (740); encoding a binary sequence according to a true occupancy image, wherein the binary sequence transmits the occupancy status for the list of pixels with unknown occupancy status (750); detecting anchoring points from the binary sequence, and encoding missing elements between the anchoring points (760); determining a first section across a third axis from the bounding volume reconstructed so far and create a list of pixels with unknown status (780); encoding a binary sequence according to the true occupancy image the sequence conveying the occupancy status of the list of pixels with unknown status (785); and detecting the anchor points from the sequence and corresponding list of pixels and encoding missing elements between the anchoring points (795).

Abstract: Methods and devices provide improved perceived quality of an audio (or other) coded signal at a low bit-rate. An input signal may be split into an outlier portion and a stationary portion. The outlier portion of the input signal may be encoded. The stationary portion may be divided into subvectors. Each subvector may be classified as trivial or non-trivial. Each trivial subvector may be encoded using a pre-defined pattern. Each non-trivial subvector may be encoded with at least one location of at least one significant sample and a sign of the significant sample.
