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`. Returns ------- data : record array with fields - row: int row position of feature - column: int column position of feature - scale: float feature scale - orientation: float feature orientation - data: array feature values TFrrowcolumnscale orientationdataSURF second_momentsign )sepzInvalid z feature file.) isinstancestropenmapintreadlinesplitnpdtypefloatfromfilesizeitemsizeOSErrorcloseview)filelikemodeffilelike_is_str nr_features feature_lendatatyper s O/var/www/html/test/jupyter/venv/lib/python3.11/site-packages/skimage/io/sift.py _sift_readr+sF(C   NN  v~~#&sAJJLL,>,>,@,@#A#A [85!% &%-.    !**,,''!+ !**,,'' 85! 5!*-%-.     ;qc " " "D yK("33bhuoo6NNNN5555666  99X  c$t|dS)Nrr$r+r%s r*rrT af % % %%r,c$t|dS)Nr r.r/r0s r*rrXr1r,)r)numpyr__all__r+rr__doc__r,r*r7sp  $KKKK\&&&&&&& & r,
