Why tesseract::ResultIterator breaks Chinese word into separate words?

I have such picture: Chinese characters

ANSWER

Answered 2022-Mar-17 at 19:18

Actually this is a correct behavior, because in Chinese some specific symbols may be as separate words. If you want to recognize such symbols together without spaces then just use the tesseract::RIL_SYMBOL instead of tesseract::RIL_WORD. Thus, you can iterate through each symbol one by one.

Most definitely font size is causing this problems. I did run it through my tesseract app and with big image the confidence level is at 81%, with smaller one it's up to 96%. Similar issue here: https://github.com/tesseract-ocr/tesseract/issues/3480

Build tesseract as DLL Dynamic link library

Asked 2022-Feb-03 at 11:26

I'm using this .NET wrapper https://github.com/charlesw/tesseract and I wanted to update the included tesseract and leptonica DLLs but after a long google search I was not able to generate them from the original tesseract and leptonica github repositories.

I already ask on the charlesw repository but did not get any reply (https://github.com/charlesw/tesseract/issues/486).

Any help on how to build the DLLs is much appreciated.

Create searchable (multipage) PDF with Python

Asked 2021-Aug-16 at 13:30

I've found some guides online on how to make a PDF searchable if it was scanned. However, I'm currently struggling with figuring out how to do it for a multipage PDF.

My code takes multipaged PDFs, converts each page into a JPG, runs OCR on each page and then converts it into a PDF. However, only the last page is returned.

...

ANSWER

Answered 2021-Aug-16 at 11:00

There are a number of potential issues here and without being able to debug it's hard to say what is the root cause.

Are the JPGs being successfully created, and as separate files as is expected?

I would suspect that pages = convert_from_path(PDF_file, 500) is not returning as expected - have you manually verified they are being created as expected?

QUESTION

Is there a way to get possible characters for a image (containing single character) in tesseract?

Asked 2021-Jul-08 at 12:53

I tried searching around in the internet, github issues and such, but was unable to find if it's possible to get the result with different possible character alternatives while using tesseract.

for example while running tesseract -l jpn --psm 10 input.png - on this image I get the output 白, but if possible I'd like to also see the other possibilities, and if possible with their confidence coefficients.

I found that it's specially useful while trying to recognize a single character as the tesseract --psm 10 will give wrong but close results for complex kanji.

Like was being recognized as 側. So, I was thinking if I could like get the 5 most probable or sth like that from the command line, then it could be great. And if it's not possible through the command line I'm also willing to see a direct programming approach using the API.

EDIT: tesseract -l jpn --psm 10 iu.png - command on results in 雨 result. On doing this on the code given in the answer I can see that the confidence is 93.68% and shows only one result. If I run the same in this image instead , I'll get 言 (99.46%) which means it is giving a sensible result, but it's only giving me a single result ignoring others. I hypothesized that it does so because the confidence is high because if I run the same command on , I get 遊 but when I run the code, I get
