@RoyiAvital, see the discussion here: Creation of Images domain.
I do think that an image processing domain would be worthwhile, but there hasn’t been a large volume of discussion in all of the JuliaLang Discourse regarding image processing or computer vision. It could be a chicken and egg thing–there’s not much discussion because there’s no forum, and there’s no forum because there hasn’t been much discussion. But it could also be that not many people are using Julia for image processing yet (despite the, IMHO, very well designed Images.jl and related packages).
Cheers,
Kevin
