Hi Zdenko, Thanks I managed to get the OCR result by cropping out all the white edges from the "SIGN IN" image. Interestingly, I didn’t need to crop the white edges from the "SIGN IN WITH FACEBOOK" image to achieve a successful result. Although both images appear quite similar—white text on a dark background, with some white edges—the results differed between them. Could you please provide more details about how you handled this, so I can better manage similar cases in the future?
