Table 2 The RMSE, execution time, number of detected, matched, and inlier feature points, number of not-found translations, and the number of invalid translations of 1603 textured pair tiles from image collections of the Tak dataset using region-based and feature-based pairwise registration methods considering the overlapping region for feature extraction. Note that the mean ± std is reported and a ranked ANOVA test for RMSE of corrected images is F(11, 18,894) = 139.77, p = 0.0 < 0.001.
