On: Don't use text pixelation to redact sensitive info...

[daniel_iversen]

Wouldn't an algorithm just like this one also be able to work on really blurry (i.e. far away zommed in) photos too? Especially with a huge corpus of trained content?

[praptak → daniel_iversen]

In principle, yes. But real world blur is much less deterministic than pixelation algorithms, so this would limit the usefulness of this technique.

[sandos → praptak]

Yes adding a geometric transform for perspective would make this a number of dimensions more difficult to solve.
