The proposed method first uses common subtractive clustering locating method to acquire video object position and moving object number of each frame. Then, the proposed algorithm uses fuzzy C-means clustering algorithm to further cluster the moving object foreground pixel samples. Finally, matrix analysis theory for calculating eigenvalues and eigenvectors of covariance matrix is applied to compute the object scale and orientation parameters.

Based on extended Linsker's network developed by Wimbauer et al.,we build a model for the receptive field of toad's R3 ganglion cell and a model for the receptive field of the nLM neuron of pigeon. Computer simulations on the 'head/tail preference' property,the configurational selectivity of the R3 neuron,and the selectivity for contrast,direction,orientation and the length of the moving edges of the nLM neuron,have been made. The simulation results are consistent with the physiological experiments qualitatively.
