this is a case where we need to know if an image has text in it. It is different from OCR.

The algorithm which is considered to be best to date is Stroke Width Transform. It was designed by Ephstein under Microsoft in 2010. It doesn't use any machine learning purposes.

You can get more details from this paper : Detecting Text in Natural Scenes with Stroke Width Transform

Or watch a video about this.

There is an implementation of this algorithm here.
