| 中文摘要 | 多视视频编码是实现自由视角电视和三维立体电视等应用的关键技术。为了有效地提高视间预测的效率,该文基于摄像机几何模型,提出了一种新的视间预测算法,其特点是利用摄像机参数和深度信息对视差矢量进行预测,并运用亮度补偿工具和亚像素插值技术减少视差补偿误差。将新的算法集成到目前最新的多视视频编码框架H.264/AVCMVC中后,实验结果表明,新的算法最高能节省32.82%的码率,编码增益最高可达2.067dB。; Multi-view video coding(MVC) is a fundamental encoding technique for FTV(free-viewpoint television) and 3DTV(3D television).That effectively improves the inter-view prediction efficiency.An inter-view prediction algorithm based on a camera geometry model was developed where the camera parameters and depth information are used to predict the disparity vector.Illumination compensation and sub-pixel interpolation are also used to reduce the distortion of the disparity compensation.H.264/AVC MVC is used as an example to illustrate how the method can be integrated with conventional video coding algorithms.Comparisons show that the bit rate can be reduced by up to 32.82% by this algorithm with a coding gain of up to 2.067 dB. |
