“In the future everybody will be famous for 15 minutes.” Andy Warhol Marilyn Monroe (Andy Warhol, 1964) Application Contribution Skin models Tested using our algorithm Purpose
An interactive art installation 15 second of fame
Hardware Digital camera LCD monitor computer USB
Software input photo finding faces transformation color filter pop-art portrait illumination compensation learning 15 second loop
Roadmap Face detection algorithm Skin labeling approaches Illumination compensation approaches Pop-art color transformations Summary
Face detection method #1 Our original face detection method
Face detection method #2 Simplified face detection method
Skin labeling approaches #1 Our model in RGB colour space
Skin labeling approaches #2 Model #1 in UV colour space Hsu et al (TPAMI’02) C b C r YY
Skin labeling approaches #3 Model #2 in UV colour space Hsu et al (TPAMI’02) C b C r
Skin labeling approaches #4 – Results #1
Skin labeling approaches #4 – Results #2

Eliminating the influence of non-standard illumination Grey World Modified Grey World White-Patch Retinex Color by Correlation
Color transformations + color-balance + random coloring + posterize + hue-saturation + color-balance + posterize + hue-saturation = 17 universal filters Different displaying ordering of portraits
Conclusions Graz (Austria), Zagreb (Croatia) Leonardo (MIT Press) Rent/Buy For our detection scheme the 3D Color space proved better!!! The people accepted application very well
