Generating a painting from a picture

[Rishabh Raj]

I read a few publications on the subject. Processing an image per pixel to 
generate a few effects seems to be straightforward.

But most of the literature is based on modelling brush strokes in paintings 
which are modeled as cubic B spline curves [1]. Do we have support for 
generating curves while processing an image?
