OCR not reading tiff file effectively #25

Closed ShekharDewan closed 6 years ago

ShekharDewan commented 6 years ago

The included tiff file (SampleTiff.tiff) does not seem to be well processed by the OCR. I tried targetting it with PerformOCROnImage.Run() and tried just uncommenting OCROnMultipageTIFF.Run(), both with lackluster results. Both output only one line (similar in both cases), and its unclear where the line is coming from in the tiff file.

@RoomTemprature,

You are correct. Output after performing Aspose.OCR operation on this image is not correct. This image has colored background. At the moment, Aspose.OCR has issues with colorful backgrounds. This issue has already been logged into our system.

We are sorry for the inconvenience.

Thanks for the update. The OCR also seems to struggle with crowded images, such as sample1.jpg, but I'm guessing that's not a simple fix either. That image doesn't have a colored back ground.

We will look into it along with the issue already reported earlier.
