Figure 6

Estimated disparity images of the combinations of the cost and the image filter, according to each stereo matching method over the synthetic active dataset. All attributes of the active IR images were set to default values. In SGM, the columns equal to the max disparity value are not used in the left image because the corresponding pixels in the right image cannot be used for comparison. Therefore, missing pixels appear at the left edge of the image [33]. (a) Window, SAD. (b) Window, Mean/SAD. (c) Window, LoG/SAD. (d) Window, BilSub/SAD. (e) Window, Rank/SAD. (f) Window, Census.
