This routine reads SIFT or SURF files generated by binary utilities from http://people.cs.ubc.ca/~lowe/keypoints/ and http://www.vision.ee.ethz.ch/~surf/. This routine *does not* generate SIFT/SURF features from an image. These algorithms are patent encumbered. Please use :obj:`skimage.feature.CENSURE` instead. Parameters ---------- filelike : string or open file Input file generated by the feature detectors from http://people.cs.ubc.ca/~lowe/keypoints/ or http://www.vision.ee.ethz.ch/~surf/ . mode : {'SIFT', 'SURF'}, optional Kind of descriptor used to generate `filelike`.
