Portrait Virus Update

So i checked in recently with Michael Wright's Portrait Virus blog. Over 10 years of posts. Keep them coming Michael. The image above is a quick re-paint of the latest self portrait Michael posted on his site.

StackFilter1 Movie

StackFilter 1 from john dalton on Vimeo.

I've recently been trying some experiments using stack filtering to create movies. This particular example stackfilters the spatially aligned siggraph 2010 portrait virus paintings with a series of different temporal image processing operations in Studio Artist 4.

Here's a link to the full size video on my vimeo site. If you search on the stackfilter tag there you can check out other examples of constructing animations based on stack filtering effects.

Mutation 51

I've got 2 mutations here, the first based on the spatially normalized self portraits and the second on the original self portrait stack. A temporal slit scan through the entire portrait stack was used for both examples. Note how the normalization makes a big difference to get feature coherence in the final output for this kind of processing.

Mutation 50

A seven frame window through the original self portrait stack was used as input to a temporal rank min-max stack filter to generate this portrait.

Mutation 49

A seven frame temporal processing window was used with the temporal rank median filter to generate this portrait from the original self portrait stack.

Mutation 47

This portrait was generated by stack filtering the original set of self portraits with the temporal difference1 filter.

Mutation 46

This portrait was generated by stack filtering the original set of self portrait images with the temporal difference1 filter.
