摘要: 提出基于频率敏感三维自组织映射的立体视频视差估计算法,视差预测采用基于亮度分类频率敏感三维自组织映射(Classified Frequency Sensitive Three-Dimensional Self-Organizing Map,CFS-3DSOM)的视差模式识别(Disparity pattern recognition,DPR)算法。其基本思想是对视差图像的低亮度区域和高亮度区域分别进行预测,在训练模式库时引入频率敏感方法。实验表明,与传统基于块的视差估计算法相比,CFS-3DSOM-DPR算法的视差预测图像的平均峰值信噪比提高了0.78~1.78dB,时间减少了70%。
