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?

Hi Rishabh,
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.html shows how 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. ( http://scikit-image.org/docs/dev/auto_examples/applications/plot_geometric.h...)
Hope you have fun with this project! Emmanuelle

Hey,
I'm working on a project in which the objective is to create a painting from a picture taken with a normal camera. This painting could be an oil painting or we could try and mimic some specific artist.
I understand this might not be achievable in a very good way by just image processing itself but I'm curious about what is achievable with stroke and simple pattern recognition for a base result.
Is there support in scikit-image along these lines? Any other inputs are welcome.
Best, Rishabh
