Perform OCR Operation over an Image using Aspose.OCR for .NET

Dear Colleagues

We try to get the ocr running for our application. We would like to get german text out of printscreens. We have seen your help site with the different characters: and found there also german characters like ö ä ü, …

From the attached “sample.jpg” the ocr text is:

ÖäfüAE-Cb (according to the sample.jpg it should be: öäüAEO

Faraway from the sample.jpg, even it has a good resolution and it is arial with no background.

                string dataDir = @"c:\temp\";
                AsposeOcr api = new AsposeOcr();
                string result = api.RecognizeImage(dataDir + "sample.jpg");
                File.WriteAllText(dataDir + "sample.txt", result);

We are using aspose.ocr

What’s wrong here?

Thanks a lot for your support.

Dear Asad

Is there any news on that topic?

We are continuously working over improving the recognition quality in the API. The latest version Aspose.OCR for .NET 20.7 has better recognition performance. Would you kindly try it and let us know about your feedback. Furthermore, we will inform you as soon as the ticket is closed.

I tried with version 20.8 but still very poor recocnition. A had a very clear picture with:


and this ist recognized as:


************* Trial Licenses *************

Can you please send that information to your developers. Every scanner software can recognize this 10x better.
