Circular feature model of 3D object and cylindrical model is embedded into complex background. The parameters λ1,λ2,λ3 for the three image sequences from left to right are [1,1,0.1],[1,1,1],[1,1,1], respectively. The parameters λin,λout for the three image sequences from left to right are [1.0e−6,1.0e−7],[8.0e−6,2.0e−7],[8.0e−6,2.0e−8]
