摘要
针对静止自由立体图像数据量大的问题,摆脱了传统以JPEG标准进行静止图像压缩的思路,根据视点数不同,选择了相应的关键视点编码为I帧,其余的分别编码为P帧和B帧,充分利用了H.264的帧内、帧间预测等工具对其进行压缩。实验结果表明,基于H.264的压缩算法比基于MPEG-2、JPEG的压缩算法效率更高、图像自由立体效果更好。
To compress still stereoscopic pictures with huge amounts of data, H.264-based still stereoscopic pictures compression scheme was studied. Adopting H.264 coding tools to achieve this compression was discussed with reference to a number of related articles. Still stereoscopic pictures compression schemes based on H.264, MPEG-2 and JPEG were compared through the experiments. The results show that with H.264-based scheme higher compression rate can be achieved, higher quality compressed multi-stereo pairs can be acquired and the exact binocular disparities between multi stereo pairs can be better preserved.
