ADR algorithm question

Can you give me a rough idea about how the ADR algorithm works so I can present better images to it for recognition? I'm trying to recognize US tax return forms and I get quite a number of false matches. I've added up to 8 images into a template with still no luck. The documents I'm trying to match ...

Deskew & ROI relationship

If I deskew an image do I also need to correct any ROI used by my code? Or should I expect that a pure skew error would not impact the ROI that I might be targeting? It appears that the deskew method changes the image passed in the call and does not create a new image. Is this correct? Thus any any ...

OCR speed and threading

In using the OCRTesseractDoOCR() method I see it does not take a threading argument like OcrPages() does. Is there any way to enable OCRTesseractDoOCR() to take full advantage of the hardware cores available on a server to speed the processing? I am seeing times of 7-9 seconds per page to do the OCR...

Re: Random triangles on PDF

Cedric I have downloaded 12.0.44 and tried toe OCR example project and the problem is gone. I will deploy to my server and continue testing in my application, but so far so good. Do you have a root cause for the triangle issue?

Random triangles on PDF

I have downloaded a tax form from the IRS website. https://www.irs.gov/pub/irs-pdf/f1065.pdf If I open this with the GdPicture sample OCR project I get black triangles randomly on the screen. Has anyone seen this before? Is this a function of the raw PDF or is this something to do with GdPicture? Is...

Issue disposing of image

I am using the following code to loop through a number of PDF documents and doing OCR on them. The issue I am having is that the picture is not being disposed and the new picture loaded. It seems to just continually process the first PDF uploaded. In the code below the foreach loops through the PDF ...

Get image count method?

I'm reading the documentation and I can't seem to find a method that will return handles to all of the available images or PDFs (GdPictureImaging or GdPicturePDF). Maybe I'm not looking for the right keyword. Is there such a method? I want to ensure I'm disposing of all images at the end of a proces...
