Hello i am trying to read text from a camera stream any working packages to recommend ?

i tried the cob_read_text from cob_object_perception but i got the following error:

Correlation:/home/panos/catkin_ws/src/cob_perception_data-indigo_dev/cob_read_text_data/fonts/new_correlation.txt cob_read_text: /home/panos/catkin_ws/src/cob_object_perception-indigo_dev/cob_read_text/common/src/text_detect.cpp:122: void DetectText::readLetterCorrelation(const char): Assertion `fin >> number' failed.

Maybe a package that even extract text from an image will be useful if there is no working package that extract from a camera stream.Thank you
