ofxLogPolarPOC

Scale and Rotate-invariant Image matching using Openframewrks.

example

Algorithm

  • using POC(Phase only correlation) with Log-Polar Transform of 2D FFT(Mellin Transform).
  • Polar Transform of 2D FFT has rotation invariance.
  • Logarithmic Transform of 2D FFT has scale invariance.
  • 2D FFT has shift invariance.

Dependency

  • OpenFrameworks 0.10.1
  • ofxCv
  • ofxOpenCv
  • fftm.hpp & fftm.cpp
  • XCode 10.12.x
  • OSX Mojave

Next Plan

  • Rotation & Scale Restotation.
  • Panoramic merge using Image Sequence.
