Text detection using connected component labelling

Question

I'm creating a project where I have to detect text regions in an image and localize text lines. This I have not yet implemented, in this project after the initial image pre-processing I will generate an edge map and then use CCL (two-pass algorithm) to localize text lines.

My question is after the edge detection part all edges including those that are not text will be detected, so how do I filter out the non-text regions? Please, help this is the first time I had to make something like this.

please excuse my English

This would be an extremly difficlult problem, if you are dealing with pictures alone. There are projects here on hte web site that detects numbers and you should be able to do the same with text:
