Description

Hi,

Using opencv_text (opencv_contrib) library with Tesseract results in memory leaks, as according to the Tesseract API the char array returned by method GetUTF8Text() have to be deleted by the user. In the module:

file: opencv_contrib-master/modules/text/src/ocr_tesseract.cpp
line 143: output = string( tess.GetUTF8Text());
