A method for detecting moving objects based on dual-threshold and multi-resolution Gaussian mixture models and for eliminating shadow based on multi-attribute(named MRPS)is proposed to address the problem of low foreground mask detection accuracy caused by cast shadows under natural scene in detecting moving objects. First
the MRPS detects moving motion mask using the dual-threshold and multi-resolution Gaussian mixture models and overcomes the influence of illumination change and light shadows using the computational color model according to the point's color properties under different resolutions. Then
the potential shadow areas are determined in the motion mask from the optical properties
and the properties of the potential shadow areas are classified through analyzing the location properties for their outer contours. Finally
the backlighting object areas connecting with the shadows is recovered and the real object areas in the moving mask are retained by analyzing edge properties. The proposed algorithm is verified using the shadow sequences in the public test image sequences and compared with Dirichlet processes Gaussian mixture models(DPGMM)method. Experimental results show that the foreground obtained by the MPRS overcomes the influence of cast shadows more effectively
and the foreground detection precision increases by 7.08%.
