Abstract: Rebinning methods and arrangements are provided that significantly improve the 3D wavelet compression performance of the image based rendering data, such as, e.g., concentric mosaic image data. Through what is essentially a selective cutting and pasting process the image data is divided into stripes that are then used to form a set of multi-perspective panoramas. The rebinning process greatly improves the performance of the cross shot filtering, and thus improves the transform and coding efficiency of 3D wavelet codecs. While the region of support after rebinning may cease to be rectangular in some cases, a padding scheme and an arbitrary shape wavelet coder can be implemented to encode the result data volume of the smart rebinning. With an arbitrary shape wavelet codec, the rebinning outperforms MPEG-2 by 3.7 dB, outperforms direct 3D wavelet coder by 4.3 dB, and outperforms a reference block coder (RBC) by 3.2 dB on certain tested concentric mosaic image scenes. Hence, the rebinning process nearly quadruples the compression ratio for selected scenes. Additional methods and arrangements are provided that include selectively dividing the image data into slits and rebinning the slits into a huge 2D array, which is then compressed using conventional still image codecs, such as, JPEG.

Abstract translation: 提供了重新组合的方法和布置，其显着地改善了基于图像的渲染数据（例如同心马赛克图像数据）的3D小波压缩性能。 通过本质上选择性的切割和粘贴过程，图像数据被分成条纹，然后用于形成一组多视角全景。 重组过程大大提高了交叉滤波的性能，从而提高了3D小波编解码器的变换和编码效率。 虽然重组后的支持区域在某些情况下可能不再是矩形，但是可以实现填充方案和任意形状的小波编码器来对智能重新归类的结果数据量进行编码。 使用任意形状的小波编解码器，重新排序的MPEG-2优于3.7 dB，优于直接3D小波编码器4.3 dB，在某些测试的同心马赛克图像场景上优于参考块编码器（RBC）3.2 dB。 因此，重新组合过程几乎是所选场景的压缩比的四倍。 提供了附加的方法和布置，其包括选择性地将图像数据划分成狭缝并将狭缝重新划分成巨大的2D阵列，然后使用诸如JPEG的常规静止图像编解码器进行压缩。
