摘要
文中提出了一种视差约束的3D立体视频重新定位方法,该方法同时将双目视频调整为新的纵横比,并将深度感知进行重新映射。建立畸变能量建模来防止视频内的目标区域形变,通过模拟视差变化能量来约束空间域和时间域中的视差范围,实现了深度映射的稳定性。运用原始立体视频生成不同显示分辨率的高感知质量的图像版本,克服了能量模型中目标分辨率的非均匀性和像素形变的干扰。最后通过实验分析验证了所提方法的有效性。
A disparity-constrained 3D stereo video relocation method is proposed.It simultaneously adjusts binocular video to a new aspect ratio and re-maps depth perception. Distortion energy modeling is established to prevent the target area from deforming in video. The disparity range in spatial domain and time domain is constrained by simulating disparity change energy,and the stability of depth mapping is achieved. The original stereo video is used to generate high-quality image versions with different display resolutions,which overcomes the non-uniformity of target resolution and the interference of pixel deformation in the energy model. Finally,the effectiveness of proposed method is verified by experimental analysis.
