The expansion for the browser recognizes better than through the API

OCR.space Free OCR API
1

Hello!

Thank you very much for your hard work—it is highly appreciated.

I am using your product via the API and have the following question:

There is a type of image where text recognition works very well in the Opera/Chrome browser extension. However, recognition through the API is quite poor. Could you please let me know what I might be doing wrong?

In general, if the text is simple, it is recognized well, but more complex texts are recognized poorly, even though the browser extension handles them correctly.

I am attaching links to the images and code:

        :param filename: Your file path & name.

    payload = {

        with open(filename, 'rb') as f:
            r = requests.post(

            print(f"Error: Unable to connect to OCR.space API. Status code: {r.status_code}")
            return None

What am I doing wrong? :slight_smile:

Hi,

Your screenshot is from Copyfish. This extension uses scale=true and ocrengine=2 as the default settings.

So two suggestions for your API call:

(1) Use scale = true

'scale': "true",

(2) And maybe also use OcrEngine 2:

'ocrengine': "2",

These parameters worked for me.

    payload = {
               'isOverlayRequired': overlay,
               'apikey': api_key,
               'language': language,
                'scale': "true",       
                'ocrengine': "2"       
               }

Thanks it worked for me, now it recognizes more complex texts. Good luck to you.
