光场图像的双域压缩加密算法研究
摘 要
光场图像技术是一种新兴的三维成像技术，其具有高分辨率、
高灵敏度和高动态范围等优点。在光学远程通信、医学成像、
安全监控等领域具有重要的应用价值。然而，光场图像具有高
维、大数据量的特点，传统的压缩加密算法无法满足其处理要
求。本文提出了一种基于双域压缩加密算法的光场图像处理方
案。该方法首先将光场图像转换为空间域和角度域两个子图像，
然后采用不同的压缩和加密算法对两个子图像进行处理，最后
以合理的方式合并成最终的光场图像。实验结果表明，该算法
具有较好的保密性和压缩效果，适用于光场图像在远程传输和
存储过程中的处理需求。

Abstract
Light field imaging technology is an emerging 3D
imaging technology with high resolution, sensitivity,
and dynamic range. It has important application values
in the fields of optical remote communication, medical
imaging, and security monitoring. However, light field
images have high dimensionality and large data volume,
and traditional compression and encryption algorithms
cannot meet their processing requirements. In this
paper, a solution for light field image processing
based on dual-domain compression and encryption
algorithm is proposed. This method first converts
light field images into two sub-images of spatial and
angular domains, and then uses different compression
and encryption algorithms to process the two sub-
images. Finally, they are merged into the final light
field image in a reasonable way. Experimental results
show that the algorithm has good confidentiality and
compression performance, which is suitable for
handling the processing needs of light field images in
remote transmission and storage.
Keywords: Light field images, dual-domain compression
and encryption, spatial domain, angular domain,
confidentiality, compression performance.
1. 研究背景和意义
光场图像是指在图像传感器接受到光的每个方向与位置信息时
获取的图像数据，是由六维光学数据表示的三维图像。与传统
的数字图像不同，光场图像可以提供多个视角下的图像数据，
具有更高的信息量和更加真实的效果。光场图像可以应用于虚
拟现实、全息成像、三维重建等领域，有着潜在的商业应用和
研究价值。
