Sketches for Pasts and Presents I

   
Yellowish image = Past (Static or 3 sec. buffered image)
Middle = Painting with a layer of motion mask (lowered opacity)
Realistic image = Current Frame shown inside motion mask.
The motion mask layer is separate from image layers (so not by averaging frames). Also experimented with detecting fast and slow motion (different thresholds and internal buffer durations). High treshold is good for detecting trees.
The layering is different, motion mask opacity is not lowered.
Brute imagery.
   
Overview of previous sketches.
Motion mask layering (fades away in time, past seen in motion mask)
Present is photo-realistic.
Black helps for hiding-revealing effect.
Gives a more painterly, playful feeling.
 
   
Just the motion mask (fading in time)
Very noir, but good in capturing very suddle motion.
(because of full opacity motion mask.
