Blur all human faces in photos?

Guttorm · 01-09-2014, 12:46 PM

Hello

I am looking for a program that can detect human faces in photos and blur them so people can't recognize them. The purpose is to run a filter on a lot of street photos before it's put on the internet. Anyone seen a program like that? Or maybe I just don't know the word to search for?

You could ask about this on Google+ where most of the active people work for Google and some of them know all about this.

have a look at OpenCV and the VTK project

opencv can look for a area that "might" be a face then blur it

but
you will need to code it

Thanks!

Adding opencv to the search, I found this:

It works, kind of. But if fails to blur faces at certain distances and also people looking sideways. I think the xml file needs tweaking so can detect only "half a face" and people a bit far away. I will have to study opencv a lot to do it. So I'm not marking this thread solved, I'm still looking for a better solution.

Hi. Sounds like a difficult task unless you do it manually with the Gimp's blur tool could look into:
