ofxHomomorphicF

Spatial Domain Homomorphic Filter for Openframeworks using ofxCv

Algorithm

• Homomorphic Filter is a kind of Cepstral Technics of image.
• Ambient light has Low frequency information. But, Object light has Higher frequency info.
• Logarithmic of Power spectrum is separate two above informations and Low Stop Filtering.

How To

• Move your mouse horizontally to change Alpha param in realtime.
• Move your mouse verticallyl to change Beta param in realtime.

Dependency

• OpenFrameworks 0.10.1
• ofxCv
• ofxOpenCv
• ofxGUI
• XCode 10.12.x
• OSX Mojave

Next Plan

• FFT based Homomorphic Filtering
• Realtime WebCam Homomorphic Filtering
