Cartoonizer on face with transparent background about opencv-python-blueprints

[mbeyeler]

Interesting. I had not considered images with a transparency layer. It seems like bilateralFilter hadn't either, as they accept only 1-channel and 3-channel images. 😉

I guess you could try passing each R, G, B channel of the image separately to bilateralFilter. Have you tried that? Not sure how it will look in the end though.

P.S. Have you seen our Google Discussion Group?

Cheers,

Thank you for the response and the clever idea to filter each channel separately. I might try this. But currently I am just cutting out the black background with a face recognition tool. Which is a little bit stupid, because now I do this step twice (before and after cartoonizing)
