Semi-Automatic Text Highlighting in Images?

Greetings Overflowers,

Given that:

• I have images of documen开发者_开发问答ts with text of mixed languages
• I need this text to be highlightable (word by word) by end users
• I have this text in plain digital format already
• I will help my program to figure out where words are
• I do not want my help to be tedious to me
• I will also manually fix small inaccuracies after my program

What is the best easy help I can provide for my program to be able to draw rectangles around selected words ? What algorithm would you use for this program ? I tried OCR stuff like OmniPage Pro but they do not provide this functionality.

Regards

I have implemented a word bounding box and highlighted words in my application some years ago. You said "I have this text in plain digital format". One key component is to have coordinates of characters or words in order to map them to proper image areas. Like in searchable PDF, when you select text it is internally mapped to the image layer, and opposite selection on the image selects matching text. But even from PDF those coordinates cannot be exported I believe. If no such coordinate informaiton exists currently in your text, easiest is probably to re-OCR images with a high quality engine that can produce coordinates as part of output. If you were to use WiseTREND OCR Cloud 2.0, then XML output will produce all that detailed metadata. If coordinates informaiton exists, then all major components are there and it is just work around efficient UI design.
