基于深度感知的光场图像高维混沌加密研究
Research on high-dimensional chaotic encryption of light field images based on depth perception
摘要
Abstract
The secure transmission challenges of light field images were addressed due to their multi-view and high-dimensional structure,a high-dimensional chaotic encryption method based on depth perception was proposed.This method extracted light field depth information using polar plane imaging techniques and structural tensor methods,while suppressing depth errors in occluded and weakly textured scenes through strategies such as intra-block median threshold-ing and adaptive filtering.Subsequently,a high-dimensional chaotic system driven by image hashing generated a multi-channel key stream,enabling adaptive pixel scrambling and diffusion based on depth perception.The system incorpo-rated a multi-level encryption mechanism,including view-level global scrambling,pixel-level global scrambling,block-wise depth-aware local scrambling,multi-round depth-enhanced diffusion,and cross-view block exchange.Experimental results demonstrate that this scheme establishes a comprehensive light field image encryption process,exhibiting supe-rior overall performance in terms of security,robustness,and ciphertext quality analysis,which provides an effective so-lution for the secure protection of light field images.关键词
