摘要:

为完成多种环境下针对不同物体的运动检测,提出了基于光照辐射的光流场模型。首先,经由通用动态图像模型在克利福德代数域上的分析,解释并修正了通用模型的参数;然后,利用克利福德代数域上的推导结果与后期实验数据,结合运动视觉产生原理与光照辐射理论,提出了基于光照辐射的光流场模型,并利用梯度场提高其准确性;最后,对此模型给出总变分法。对比实验结果显示,文中提出的模型具通用性,并能在不同光照条件下获得准确且连续一致的光流场。

Abstract:

Proposed in this paper is an illumination radiation-based optical flow field model for the motion detectionof various objects in different environments. In the investigation,first,the parameters of the general dynamic imagemodel are explained and amended in the Clifford algebra region. Then,according to the results deduced in the Cliffordalgebra region and obtained from experiments,a new optical flow field model is proposed based on the principleof movement vision-generating principle and the illumination radiation theory,to which a gradient field is appliedfor the purpose of improving the accuracy. Finally,a total variation algorithm is presented for the proposed model. Experimental results show that the proposed model can achieve accurate,continuous and consistent optical flowfields for the purpose of being generally used in different illumination conditions.
