... named the Scale Invariant Feature Transform (SIFT), as it transforms image data into scale- invariant coordinates relative to local features An important aspect of this approach is that it generates ... these approaches are yet fully affine invariant, as they start with initial feature scales and locations selected in a non-affine -invariant manner due to the prohibitive cost of exploring the full ... frames are are also more sensitive to noise than those of the scale- invariant features, so in practice the affine features have lower repeatability than the scale- invariant features unless the...
