Oops, I forgot the attachment. Here it is :-) I believe it will help you further to decide, but what it CAN do: - find whitelines - map a zone to a certainn character probability - train itself. it does NOT decide whether it is a certain character or not, this needs to be decided on the host, not

@zdenko This discussion maybe better suited for tesseract-dev forum or do you want to track it as a issue on github? ShreeDevi भजन - कीर्तन - आरती @ http://bhajans.ramparivar.com On Sat, Apr 28, 2018 at 1:19 PM, Janpieter Sollie

Re: [tesseract-ocr] tesseract 4 beta: openCL useage

Would it be a problem for you if I rewrite the opencl engine completely, and you people provide me help to link the tesseract kernel -> opencl engine parts? in attachment, I already have a list of features I'd like to port to openCL. As this uses the GPU in a heavy way, I will implement

Re: [tesseract-ocr] tesseract 4 beta: openCL useage

if I'm right, a neural net is about the engine parts, not the image characterisation rendering method, am I right? because I see many presentations, and most of them talk about the history of tesseract, but that's not what I need 2018-04-27 14:27 GMT+00:00 ShreeDevi Kumar :

Re: [tesseract-ocr] tesseract 4 beta: openCL useage

I had a quick thought about what you could offload to opencl. I will need some help from you people (I am a C programmer, not C++, at least not experienced) to do the host code, but this algorithm is perfectly optimizeable in openCL. the way I'd do it: prerequirements: - you can define 65k

Re: [tesseract-ocr] tesseract 4 beta: openCL useage

Okay, I took a quick look at the opencl code: - you are only invoking 255 (16x16) OpenCL kernels at the same time (max). This is not enough, not even for a budget GPU. - the code has some points to discuss (eg: why does it keep the kernel and the tesseract dat file in the local directory and

Re: [tesseract-ocr] tesseract 4 beta: openCL useage

a thing which I could do quite easily is search for characters with a certain offset. If you can give me 2^16 offsets to analyze, It may be an advantage to do it via OpenCL. But tdoes the network work this way? 2018-04-27 10:56 GMT+02:00 Janpieter Sollie : > I'd be

Re: [tesseract-ocr] tesseract 4 beta: openCL useage

I'd be glad to help. using tesseract 4, I am able to perform a 90% accuracy on OpenCL. I do not have any experience with neural networks (i'm just a high-school (no college educated IT-support guy with some knowledge about OpenCL), so can you recommend me some documentation to understand the

Re: [tesseract-ocr] tesseract 4 beta: openCL useage

If you have experience your help will be warmly welcomed. OpenCL is not maintained and it is on good way to be removed if maintainer/contributor will not be found. Anyway it is not used extensively, so there is a place for improvement, Zdenko pi 27. 4. 2018 o 10:21 Janpieter Sollie

Hello everyone, I have a question about the openCL selection procedure of tesseract: my output: [DS] Profile read from file (tesseract_opencl_profile_devices.dat). [DS] Device[1] 1:Fiji score is 0.202927 [DS] Device[2] 1:Ellesmere score is 1.468799 [DS] Device[3] 1:Ellesmere score is 1.468799
