Hello you all, I'm a bit surprised about the Opencv text detector module results. This is what I get using the standard textdetection sample code:

As you can see there are many false positives. Furthermore the algorythm runs very slow and if you try to scale down pictures the number of false positives increases.

All I would to know is if someone else have made a try with the textdetection sample code and gets same results or I'm getting something wrong.. I've run the tests with mac osx build if it matters.

I also tried using samples from cv::text and they all work stably only on example data
