Figure 5

Reconstruction smoothness parameters. (a) Generated matte and (b) background restoration of Figure 2b using BTBR-S with (β _a ,β _b ) = (20,0). (c) Background restoration of Figure 2b using BTBR-S but with (β _a ,β _b ) = (0,1). As shown, different configurations of (β _a ,β _b ) lead to different restorations. (d) Median filtered image of the background reconstruction of Bayesian blotch matting I. In here, a 5 × 5 median filter is applied on $I_{\mathrm{G}}=\frac{I_{\mathrm{r}}+I_{\mathrm{g}}+I_{\mathrm{b}}}{3}$. This image is used to infer the texture complexity of the original image.
