SciPy has some good B-spline (and many other interpolation) routines. We haven't re-implemented these, because we depend on SciPy. Feel free to mix-and-match these routines with scikit-image functions.

Check out the `scipy.signal` module for 1d, or `scipy.interpolate` for multi-dimensional:

Looks interesting!

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?[1] http://www.mrl.nyu.edu/publications/hertzmann-thesis/ - Section 3.

I don't think there is a generic enough algorithm that would do this

(each artist has her/his own specific style, and a specific algorithm

would have to be designed for every style I think).

Nevertheless, some of the functions in skimage can be used for this

purpose. For example,

http://scikit-image.org/docs/dev/auto_examples/plot_ncut. shows howhtml

to get a posterized, comics-like image.

You can also find geometric transformations in skimage.transform, if you

want to implement some distortion effect for example.

Hope you have fun with this project!
