Abstract: An improved texture representation method is proposed in this essay.Translation invariant wavelet transform is performed on images from video,and then video image texture representation is obtained by the low frequency coefficients which are fused with edge intensity.The improved method can extract texture and detailed features,and it can also decrease the influences brought by illumination and noise variations.Experimental results show that the improved tracking algorithm is very effectively,it can greatly improve the robustness of the tracking algorithm.
