I need to determine if a set of string is displayed in a set of images.

This is a simplified OCR case with these simplifications :

  • Fixed font family and size
  • Images are bitmaps (gif, png).
  • No antialiasing
  • I only need a true/false result, not necessarily a position index.

The main difficulties are performance. I need to test hundreds of terms in thousands of pictures.

I need pointers for algo, languages, ...

Thank you.
