Kertas kerja ini mencadangkan skim pengekodan peta kedalaman adaptif yang cekap untuk menjana imej paparan maya dalam video 3D. Imej paparan maya boleh dijana melalui interpolasi paparan berdasarkan peta kedalaman imej yang dinyahkod. Skim pengekodan peta kedalaman yang dicadangkan direka bentuk untuk mempunyai kaedah pengekodan satah bit berasaskan pengekodan kelabu baharu untuk pengekodan imej peta kedalaman yang cekap pada kawasan sempadan objek, serta skema pengekodan berasaskan DCT konvensional (H .264/AVC) untuk pengekodan imej kawasan dalam objek atau imej peta kedalaman latar belakang dengan cekap. Keputusan simulasi menunjukkan bahawa skim pengekodan yang dicadangkan, berbanding dengan skim pengekodan H.264/AVC, meningkatkan penjimatan kadar BD 6.77%-10.28% dan BD-PSNR memperoleh 0.42 dB-0.68 dB. Ia juga meningkatkan kualiti gambar subjektif bagi imej paparan maya tersintesis menggunakan peta kedalaman yang dinyahkod.

Abstract: This paper proposes an efficient adaptive depth-map coding scheme for generating virtual-view images in 3D-video. Virtual-view images can be generated by view-interpolation based on the decoded depth-map of the image. The proposed depth-map coding scheme is designed to have a new gray-coding-based bit-plane coding method for efficiently coding the depth-map images on the object-boundary areas, as well as the conventional DCT-based coding scheme (H.264/AVC) for efficiently coding the inside area images of the objects or the background depth-map images. Simulation results show that the proposed coding scheme, in comparison with the H.264/AVC coding scheme, improves the BD-rate savings 6.77%-10.28% and the BD-PSNR gains 0.42 dB-0.68 dB. It also improves the subjective picture quality of synthesized virtual-view images using decoded depth-maps.
