[tesseract-ocr] Where to find the Tesseract.dll for Tesseract OCR version v5.0.0.

[Sharp Subbu]

Dear Friends,

We have tried to find the Tesseract.dll for Tesseract OCR version v5.0.0. 
in the Tesseract git hub url ().
Kindly share the Tesseract.dll for Tesseract OCR version v5.0.0 if you have 
it, or kindly share the steps to create this dll from the Tesseract Git hub 
code.

Thanks in advance.

Regards,
Subramanyam

Use tsv output but you will still need to parse it to get line information.

Re: [tesseract-ocr] detect decimal point in amount with psm 11

[Zdenko Podobny]

   1. You got the result for the image you provided.
   2. I suggest you to use other oem
   3. I know that invoice digitalizator use different parameters for
   parsing numbers.

Re: [tesseract-ocr] detect decimal point in amount with psm 11

[Kumar Rajwani]

Hi Zdenop, As i said i know psm 6 working better in number but it not able 
to get all text in image. where psm 11 does better. So this the reason i 
want to with psm 11 but i am getting wrong amount that's the only problem i 
am facing with psm 11. So can you tell me how can i achive same result as 
you in psm 11.
Thanks

Re: [tesseract-ocr] detect decimal point in amount with psm 11

[Zdenko Podobny]

Try to use better config parameters. e.g:

$ tesseract download.png - --psm 6 --oem 0
will produce:
$ 250,941.00
$ -75,282.00
$ 175,659.00
$ -15,072 00
$ 2,860.00
$ 0.00
$ 163,447.00

legacy engine could be better for numbers

I want the opposite way. Getting ril_textline like output from passing

I think it would need to operate at RIL_SYMBOL level, not RIL_TEXTLINE.

Re: [tesseract-ocr] tessedit_create_boxfile condensed like boxaGetBox

[Zdenko Podobny]

Hello,

it is unclear for what do you do/want to do:

   - you wrote want individual chars, but request from API line
   (RIL_TEXTLINE)
   - then you wrote " Is there any way to combine individual boxes to print
   like API" so what do you want to combine?

Maybe it would be better if you provide input images and desired output...

Zdenko

[tesseract-ocr] tessedit_create_boxfile condensed like boxaGetBox

[Baris Unsal]

Hi, when I pass tessedit_create_boxfile 1 argument to tesseract it outputs 
individual chars' location. But when I use api like this:

```
Boxa* boxes = api->GetComponentImages(tesseract::RIL_TEXTLINE, true,NULL,
NULL);
for(int i = 0; i < boxes->n; i++){
BOX* box =boxaGetBox(boxes,i,L_CLONE);
api->SetRectangle(box->x,box->y,box->w,box->h);
char* outText = api->GetUTF8Text();
int conf = api->MeanTextConf();
fprintf(stdout,"Box[%d]: x=%d, y=%d, w=%d, h=%d, confidence: %d, text: %s",
i, box->x, box->y, box->w, box->h, conf, outText);
boxDestroy();
delete[] outText;
}
```
it outputs whole line like this:
Box[1]: x=36, y=84, w=246, h=14, confidence: 44, text: #Spor #siyaset 
Fanket FIliskiler

Is there any way to combine individual boxes to print like API? Thanks in 
advance.

[Kumar Rajwani]

Hey,
I am using tesseract to identify amounts in my forms. You can look below 
image for sample. i am getting perfect amount with decimal in psm 6.
but when i use psm 11 i am getting follwing output. I have to use psm 11 as 
it identify more text with compare to psm 6 in my images.

The code i am using.
print(pytesseract.image_to_string(image.crop((2000,1570,2500,2000)),
  lang="eng",
  config = '-c tessedit_do_invert=0 --psm 
11').replace("\n\n","\n"))

I want to ask if there is any changes i can do to get decimal point with 
psm 11.
