...Similar to the registration algorithm in [Henry et al. 2012; Du et al. 2011], we also perform the RANSAC algorithm to compute the correct correspondences between frames using the SIFT feature [Lowe 2004], and the semantic labels are used to cull the wrong correspondences....

...Moreover, extracting features from such images using carefully engineered descriptors like SIFT (Lowe, 2004) or GIST (Oliva and Torralba, 2001) is also likely to be suboptimal since these descriptors were designed to work well on higher resolution images....
