I am looking for a way to easily make people on photos unrecognizeable. Whenever I put any photos (usually of cities and landscapes) in my online album, I first make all the recognizeable people unrecognizeable, as I feel it is a basic matter of politeness not to publish photos of strangers.
So, I basically want to do more or less what Google does to StreetView images. Currently, I am doing this manually for each photo, by drawing ellipse selections around all the faces in Gimp and then using a blur filter on the selection.
Is there a tool that lets me do this blurring more or less in a single click? Ideally, by showing me all the recognized faces in the first step, then by letting me deselect those that I don't want to be blurred?
(Blurring out other personal details, such as car license plates, would be nice, too, but my main objective is finding such a tool for blurring out faces, as people frequently appear on photos, while the total number of legible license plates is minimal. Moreover, I'm looking for tools that blur out the faces. Pixelation may be a fallback, but it does not integrate with the rest of the image as nicely as blurring.)
I have been searching for such tools for a while already, but everything I find seems to belong into one of three categories:
- It is meant to run on smartphones rather than on desktop computers, such as this app.
- It is meant for videos, as indicated by similar questions like this or this, or this article.
- It is web-based, hence all the photos need to be uploaded to someone's server for processing, and an internet connection is required while editing the photos, such as with this service or this editor.
I am looking exclusively for software that runs on Windows and/or Ubuntu without the need for an internet connection (i.e. no cloud tools that require me to upload all the photos for processing). A free tool would be nice, but a paid-for tool is still better than no tool at all.
