Abstract
An apparatus receives a compressed bitstream including an encoded displacements bitstream and packing method information indicating whether the displacement component samples are packed in ascending order or in descending order. The apparatus video-decodes the encoded displacements bitstream to generate a displacement video frame, wherein padding is added at a bottom of the displacement video frame irrespective of whether the displacement component samples are packed in ascending order or in descending order. The apparatus image-unpacks the displacement video frame to generate an array of quantized displacement wavelet coefficients, inverse-quantizes the array of quantized displacement wavelet coefficients to generate displacement wavelet coefficients, and inverse-wavelet-transforms the displacement wavelet coefficients to generate displacement component samples.
