摘要
针对光场图像文件体积过大造成的文件传输和存储等问题,本文充分利用光场图像的相邻图像间的视差补偿性,提出一种基于HEVC视频编解码的光场图像压缩方法。为验证该方法,本文在LFSD光场数据库上实现了两个实验。第一,本文通过比较不同光场视频生成序列的压缩效果得出了一种最符合HEVC编码器的光场压缩顺序。第二,本文通过与JPEG压缩对比试验后发现本文的压缩方法比JPEG压缩方法的PSNR平均提高了6.5823d B,进而验证了该方法的可行性和有效性。
Based on the problem of light fieldcapacity, this paper put forward a light fieldmaked full advantage of light field parallax. Toexperiments on LFSD light field dataset. Firstlystorage and light filed transmission caused byits largeimage compression method combining HECV , whichverify the provided method, this paper performed two, this paper proposed a proper light field compressionorder by evaluating different kinds of light field image to video generation order. Secondly, this papercompared the put forward method with jpeg compression and the experient shows that the put forwardmethod improved 6.5832dB averagely than JPEG compression,which verified the feasibility and validityof the approach.
