Re: [tesseract-ocr] confuse whether Otsu Thresholding affects lstm training

Hi Shree, I'd love to but it is a commercial project I'm working on so I cannot share the current solution. I will try to find the old scripts I used for the first attempts. Basically it was something like this: - normalize lightness - make illumination uniform (CLAHE on HSV "V" channel) - denois

Re: [tesseract-ocr] confuse whether Otsu Thresholding affects lstm training

Hi, yes, at the very least you can use some adaptive threshold method, like OTSU, to find the best parameters. But OTSU has its own parameters so you need to fine tune those too (a little). What worked best for me was first to do a rough normalization of the images (lightness, contrast) and then d

Re: [tesseract-ocr] Making custom traineddata

Hi Shree, We have tried your traineddata file for MRZ and noticed that it does not detect the character X. Looking at https://github.com/Shreeshrii/tessdata_ocrb/blob/master/eng.MRZ.training_text We see that there are no X in there. In addition it might be good to add a couple of lines that a

If you can provide another 40-50 lines of training data (text file) I will rerun the training On Mon, 8 Apr 2019, 22:11 Jankees Korstanje, wrote: > Hi Shree, > > We have tried your traineddata file for MRZ and noticed that it does not > detect the character X. > > Looking at > https://github.co
