Real-time tesseract

[Ahmad Anis]

Hi, I am working on tesseract. My goal is to make a real-time system. So I do want it to run on almost 20+ FPS.

I am getting almost 0.5s - 1.5 s on a single frame via tesseract. I have tried alot of things to improve this speed but of no use. Some of the tried things are

* fast integer models given by Tesseract

* tessedit_do_invert=0 argument

* gray-scaling (dont need further pre-processing as images do not have noise etc.

* 4 threads via OMP_THREAD_LIMIT

* 4 processes via tessedit_parallelize

But none of these gave any improvment except tessedit_do_invert=0 and gray-scaling. I do not want to loose any chracter so can not downsize it more. 

I have implemented custom multi-processing to run 4 tesseract instances in parallel and it has boosted the speed a bit. I would need suggestions and techniques in-order to improve the latency of the OCR(cant skip the frames). I want to make it to at-max 0.1 seconds per image. If you do have any other OCR engine in mind, let me know. Thanks.

Based on information I would say get better hardware ;-)

From common know trick you implemented everything.

But generally - if anybody really need a help/support in forum(please do not use issue tracker for that):

1. There should be all necessary detail (e.g. tesseract version, OS, HW details - especially in case of speed issues)
2. Input data (image or in this case video) 
3. Test case for reproducing of problem (in this case including measuring of speed). A code snippet is not enough. Everybody is busy, so do not expect somebody will try to guess what you  are  doing and to create test app/code from scratch to solve your problem. It is YOUR problem and you are asking for FREE support. So please make it as easy as possible.
