Evaluation of Stereo Matching Costs on Images with Radiometric Differences

Hirschmüller, Heiko and Scharstein, Daniel (2009) Evaluation of Stereo Matching Costs on Images with Radiometric Differences. IEEE Transactions on Pattern Analysis and Machine Intelligence, 31 (9), pp. 1582-1599. IEEE - Institute of Electrical and Electronics Engineers. ISSN 0162-8828.



Stereo correspondence methods rely on matching costs forcomputing the similarity of image locations. We evaluate the insensitivity of different costs for passive binocular stereo methods with respect to radiometric variations of the input images. We consider both pixel-based and window-based variants like the absolute difference, the sampling-insensitive absolute difference, and normalized cross correlation, as well as their zero-mean versions. We also consider filters like LoG, mean, and bilateral background subtraction (BilSub) and non-parametric measures like Rank, SoftRank, Census, and Ordinal. Finally, hierarchical mutual information (HMI) is considered as pixelwise cost. Using stereo datasets with ground-truth disparities taken under controlled changes of exposure and lighting, we evaluate the costs with a local, a semi-global, and a global stereo method. We measure the performance of all costs in the presence of simulated and real radiometric differences, including exposure differences, vignetting, varying lighting and noise. Overall, the ranking of methods across all datasets and experiments appears to be consistent. Among the best costs are BilSub, which performs consistently very well for low radiometric differences; HMI, which is slightly better as pixel-wise matching cost in some cases and for strong image noise; and Census, which showed the best and most robust overall performance.
