Unfortunately I haven't had any luck with this either. Right now I'm trying damage control by just trying to minimize the leakage by not performing as many tesseract recognition call, but the downside of that is that I get much worse quality out of my app.
Any further suggestions on how to approach the memory leak is very welcome!
