METHOD FOR EXTRACTING FEATURE POINT BASED ON SIMPLIFICATION OF GAUSSIAN SCALE SPACE GENERATION AND APPARATUS THEREFOR

摘要

Disclosed are a method for extracting a feature point based on simplification of Gaussian scale space generation, and an apparatus therefor. The method comprises: a step of determining a pre-octave based on a first Gaussian filter applying a first sigma value to an input image; and a step of determining N Gaussian scale spaces, respectively, corresponding to each 1-N octaves (wherein, N is a natural number and larger than 1) by using a second Gaussian filter using a second sigma value based on a first Gaussian image forming the pre-octave.;COPYRIGHT KIPO 2017
