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

i tried the cobreadtext from cobobjectperception but i got the following error:

Correlation:/home/panos/catkinws/src/cobperceptiondata-indigodev/cobreadtextdata/fonts/newcorrelation.txt cobreadtext: /home/panos/catkinws/src/cobobjectperception-indigodev/cobreadtext/common/src/textdetect.cpp:122: void DetectText::readLetterCorrelation(const char*): Assertion `fin >> number' failed. [cobreadtext-2] process has died [pid 30418, exit code -6, cmd /home/panos/catkinws/devel/lib/cobreadtext/cobreadtext /home/panos/catkinws/src/cobperceptiondata-indigodev/cobreadtextdata/fonts/newcorrelation.txt /home/panos/catkinws/src/cobperceptiondata-indigodev/cobreadtextdata/dictionary/full-dictionaryeng textdetect:=/readtext/textdetect imagecolor:=/camera/rgb/imageraw _name:=cobreadtext _log:=/home/panos/.ros/log/9123a7fe-3d47-11e7-9291-848f69c69340/cobreadtext-2.log]. log file: /home/panos/.ros/log/9123a7fe-3d47-11e7-9291-848f69c69340/cobread_text-2*.log

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
