One of the critical challenges facing 3D video systems and images such as holography lies in their compression technique. High-efficiency video coding (HEVC) has emerged as one of the leading schemes to address this challenge. In this article, a novel method based on wavelet transform is presented to improve HEVC, particularly in digital holography systems (object plane). In this regard, wavelet and resizing are included in the coding process, while extra HEVC decoders and encoders are added to predict and decrease errors in the target. Simulation results reveals that the proposed algorithm reduces Bjøntegaard-Delta (BD) bitrate 17.5% (based on average BD-Rate values) compared to the original HEVC (H.265) scheme while maintaining signal fidelity and even enhancing it slightly. We observe an increased BD-peak-signal-to-noise ratio (BD-PSNR) in real and imaginary parts of digital holograms of high rate quantization values up to 1.1 dB.

3D 视频系统和全息图像等图像面临的关键挑战之一在于它们的压缩技术。高效视频编码 (HEVC) 已成为解决这一挑战的主要方案之一。在本文中，提出了一种基于小波变换的新方法来改进 HEVC，尤其是在数字全息系统（物平面）中。在这方面，编码过程中包含小波和调整大小，同时添加额外的 HEVC 解码器和编码器以预测和减少目标中的错误。仿真结果表明，与原始 HEVC (H.265) 方案相比，所提出的算法将 Bjøntegaard-Delta (BD) 比特率降低了 17.5%（基于平均 BD-Rate 值），同时保持信号保真度甚至略微增强。
