Figure 2

Problem modeling and algorithm overview. First row: Illustrating the proposed corruption model. From left: original image, corrupted image, a synthetic corruption matte α, and the corruption mask b. Second row: matte and restoration using ‘Bayesian blotch matting’ and ‘BTBR-S’. Third row: matte and restoration using BTBR-T and spatio-temporal fusion. Last row: zoomed area of the original image (a) (shown in red) and its spatial (b), temporal (c), and spatio-temporal reconstructions (d), respectively. BTBR-S generated sharp reconstruction of the blue edge, while BTBR-T generated poor reconstruction of the green edges. Nevertheless, ‘spatio-temporal fusion’ (BTBR-F) was able to minimize those two artifacts.
