The optical flow analysis of the image sequence based on the formal lattice Boltzmann equation,with different DdQm models,is discussed in this paper.The algorithm is based on the lattice Boltzmann method(LBM),which is used in computational fluid dynamics theory for the simulation of fluid dynamics.At first,a generalized approximation to the formal lattice Boltzmann equation is discussed.Then the effects of different DdQm models on the results of the optical flow estimation are compared with each other,while calculating the movement vectors of pixels in the image sequence.The experimental results show that the higher dimension DdQm models,e.g.,D3Q15 are more effective than those lower dimension ones.
