摘要
提出了一种基于相邻视点图像融合的多视点图像编码方法。该方法首先将多幅同一场景的多视点视频图像进行融合,得到一幅含有大部分信息的融合图像、边信息和视差矢量。之后对融合图像作基于NSCT的类SPIHT编,对边信息和视差矢量进行熵编码。该编码方案,通过图像融合,有效降低了多视点视频图像传输和存储过程中的信息量。解码后的图像视觉质量和实验结果表明,该方法能更有效地表示图像的边缘信息,获得比传统编码方法更高的峰值信噪比,具有实践意义。
A multi-view image coding scheme is proposed.Different sources of images are fused in to one image,and then the fusion results are encoded.The encoder utilizes the set partitioning in hierarchical trees(SPIHT) algorithm which is suitably modified to take into account the new hierarchical structure of NSCT coefficients and the correlation between them.This approach is so efficient that it provides comparable performance to JPEG2000 objectively and subjectively.The superior result of encoder,confirms the potential of this approach.
