OCR module is not usable - uses huge amout of memory and is incredible slow

Aspose.OCR Product Family
1

Hello Support,
We have a java-total license and have built a proof of concept application to test your modules word, cells (excel), slides (powerpoint), diagram (visio), pdf (conversion cgm to png) and ocr.

All of these modules are more or less working, but ocr module is not usable:

  • Uses huge amout of memory
  • Is incredible slow (for one image page about 10 seconds on my Macbook pro M1-max and more than 30 seconds within Openshift-Pod.
    What is the reason for this behaviour?
    Currently, we use software from Leadtools which works ok (about 1 second for one page).

Can you please provide more details about the image types you are processing with the OCR module and the specific version of Aspose.OCR you are using?

We are using Version 24.10.0 of Aspose-ocr.
It’s very strange:

  • locally with Macbook M1-max some images take 2-3 seconds, others take 15 seconds or more
  • on Openshift-Cluster same images takes minutes or service (pod) crashes, due to exceeded memory (1,5 GB are allowed)

Our code:
AsposeOCR api = new AsposeOCR();

  // Set recognition options
  RecognitionSettings settings = new RecognitionSettings();
  settings.setLanguage(Language.Eng);

  settings.setDetectAreasMode(DetectAreasMode.PHOTO);

  OcrInput images  = new OcrInput(InputType.SingleImage);
  images.add(file.getInputStream());

  // Fast recognize images
  long d = System.currentTimeMillis();
  List<RecognitionResult> results = api.Recognize(images, settings);
  d = System.currentTimeMillis() - d;

Only DetectAreasMode.PHOTO delivers result.
