Abstract EN
Multiview video consists of multiple views of the same scene.
They require enormous amount of data to achieve high image quality, which makes it indispensable to compress multiview video.
Therefore, data compression is a major issue for multiviews.
In this paper, we explore an efficient fractal video codec to compress multiviews.
The proposed scheme first compresses a view-dependent geometry of the base view using fractal video encoder with homogeneous region condition.
With the extended fractional pel motion estimation algorithm and fast disparity estimation algorithm, it then generates prediction images of other views.
The prediction image uses the image-based rendering techniques based on the decoded video.
And the residual signals are obtained by the prediction image and the original image.
Finally, it encodes residual signals by the fractal video encoder.
The idea is also to exploit the statistical dependencies from both temporal and interview reference pictures for motion compensated prediction.
Experimental results show that the proposed algorithm is consistently better than JMVC8.5, with 62.25% bit rate decrease and 0.37 dB PSNR increase based on the Bjontegaard metric, and the total encoding time (TET) of the proposed algorithm is reduced by 92%.
