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 TFSIFTrowcolumnscale orientationdataSURF second_momentsign )sepzInvalid z feature file.) isinstancestropenmapintreadlinesplitnpdtypefloatfromfilesizeitemsizeOSErrorcloseview)filelikemodeffilelike_is_str nr_features feature_lendatatyper s N/var/www/html/test/engine/venv/lib/python3.12/site-packages/skimage/io/sift.py _sift_readr+shF(C N  v~#&sAJJL,>,>,@#A [885!% &%-.   !**,'!+ !**,' 885! 5!*-%-.    ;;qc "D yyK("3"33bhhuo6N6NNNn566  99X ct|dS)Nrr$r+r%s r*rrT af %%r,ct|dS)Nr r.r/r0s r*rrXr1r,)r)numpyr__all__r+rr__doc__r,r*r7sA  $K\&&&& && r,
