I am looking for a program that can remove from an image a given text.

E.g. if given the image

enter image description here

and the text Max it should return something like:

enter image description here

where the text isn't visible anymore.

It should work on Microsoft Windows. Gratis is preferable.

    tesseract-ocr and imagemagick (-draw rectangle) could be used as basic elements, but I don't a tool that does this out-of-the-box... – Nicolas Raoul♦ Apr 26 '16 at 5:21

  • @Mawg I don't want to have to search for all occurrences of the text in the image myself – Franck Dernoncourt May 27 '16 at 14:30
  • Sorry, that wan't clear from your question (or maybe I misunderstood). Obviosly some form of OCR is required. This could be a tricky one. – Mawg says reinstate Monica May 27 '16 at 14:32

I use Greenshot to add obscurification to parts of images. It's a free program compatible with Windows. It allows you to set how many boxes per pixel you want as well. Here below is an example using the image you provided above,

You can also increase the pixel size to make it use bigger blocks,

Greenshot (free)

Greenshot is a light-weight screenshot software tool for Windows with the following key features:

  • Quickly create screenshots of a selected region, window or fullscreen; you can even capture complete (scrolling) web pages from Internet Explorer.
  • Easily annotate, highlight or obfuscate parts of the screenshot.
  • Export the screenshot in various ways: save to file, send to a printer, copy to clipboard, attach to e-mail, send Office programs or upload to photo sites like - Flickr or Picasa, and others.

…and a lot more options simplifying creation of and work with screenshots every day.

Being easy to understand and configurable, Greenshot is an efficient tool for project managers, software developers, technical writers, testers and anyone else creating screenshots.

    Thanks, is there any way to specify which text I want the program to remove? ( i.e., I don't want to have to search for all occurrences of the text in the image myself ) – Franck Dernoncourt Apr 26 '16 at 3:08

    @FranckDernoncourt Unfortunately, no - maybe a combination of OCR and this software could help? I'm unaware, though, of software that does both. – Tom Apr 26 '16 at 3:31
