چکیده

Abstract. This paper presents a novel algorithm for rate-complexity scalable multi-view image coding using an adaptive disparity-compensated (DC) wavelet lifting scheme. First, image regions of multi-view images are prioritized by counting matching points. The proposed algorithm selects either Haar, 5/3, or our proposed multiple picture reference DC wavelet lifting adaptively. The selection criterion is based on the bit budget constraint, the complexity budget constraint, and the priorities of image regions. Then, the low-pass and high-pass subbands, obtained from the DC wavelet lifting, are further decomposed by a spatial wavelet transform. The resulting wavelet coefficients are entropy encoded with the SPIHT codec. Experimental results show that the proposed algorithm provides an efficient adaptive framework for multi-view image coding.

Multi-View Image Coding with Wavelet Lifting Scheme

In this paper, we present a novel multi-view image codec based on a wavelet lifting scheme. The proposed algorithm applies the disparity estimation and compensation with the lifting scheme. It is very efficient in terms of compressions performance, memory requirements and fast. To get the highest multi-view image coding efficiencies, two hybrid predictions are proposed; one for effective compre...

Lifting-based invertible motion adaptive transform (LIMAT) framework for highly scalable video compression

We propose a new framework for highly scalable video compression, using a lifting-based invertible motion adaptive transform (LIMAT). We use motion-compensated lifting steps to implement the temporal wavelet transform, which preserves invertibility, regardless of the motion model. By contrast, the invertibility requirement has restricted previous approaches to either block-based or global motio...

INTRA−ADAPTIVE MOTION−COMPENSATED LIFTED WAVELETS FOR VIDEO CODING (WedAmPO4)

This paper investigates intra−adaptive wavelets for video coding with frame−adaptive motion−compensated lifted wavelet transforms. With motion−compensated lifted wavelets, the temporal wavelet decomposition operates along motion trajectories. However, valid trajectories for efficient multi−scale filtering have a finite duration in time. This is due to well known effects like occlusions or inacc...

Rate Distortion Analysis and Bit Allocation Scheme for Wavelet Lifting-Based Multiview Image Coding

This paper studies the distortion and the model-based bit allocation scheme of wavelet lifting-based multiview image coding. Redundancies among image views are removed by disparity-compensated wavelet lifting (DCWL). The distortion prediction of the low-pass and high-pass subbands of each image view from the DCWL process is analyzed. The derived distortion is used with different rate distortion...
