...In the field of CV, the surface measurement is generally performed using stereopair depth maps (Strecha et al., 2003; Pollefeys et al., 2004; Pénard et al., 2005) or multi-view methods aiming at reconstructing a surface which minimises a global photometric discrepancy function, regularised by…...

...We use a combination of two different kinds of wide baseline features, namely a rotation reduced and colour enhanced form of Lowe’s SIFT features (Lowe, 1999), and the invariant column segments we developed (Goedemé et al., 2004)....

...This allows for the use of more distinctive image descriptors than the rotation-invariant ones used by Schmid and Mohr, and the descriptor is further modified to improve its stability to changes in affine projection and illumination....

...For the object recognition problem, Schmid & Mohr [19] also used the Harris corner detector to identify interest points, and then created a local image descriptor at each interest point from an orientation-invariant vector of derivative-of-Gaussian image measurements....

..., Schmid & Mohr [19]) has shown that efficient recognition can often be achieved by using local image descriptors sampled at a large number of repeatable locations....
