摘要
针对彩色图像序列光流场计算问题并结合现有光流场计算模型,提出3种将局部彩色光流计算模型与全局彩色光流计算模型相结合的混合光流估计模型,从而有效利用局部光流模型计算精度高及全局光流模型可得到致密光流场的优点,并将3种模型进行比较,给出数值实验结果。
Referenced presented models of optical flow computing, three models of color image sequence optical flow computation with local and global methods combined for color optical flow computing are presented in this paper. The combined models have the advantages of high precision of local model and density of global model. And the models presented are compared with each other. The number experiments results are presented.
