In case Rectangle is of bigger width- text does not come properly or comes blank

Aspose.OCR Product Family

Hi,

I am using Aspose.OCR in my .net application. I have taken a trial version. Initially when i have tested it looks working fine. But when i have started using bigger rectangles, it started producing wrong results.
For example in my attached image if i use (x,y,width, height) as (50,440,150,30) it gives me correct result which is “James Donovan” but if i increase the width (50,440,300,30) it shows text as blank.

Also if i use rectangle 53,533,820,30 then text supposed to be “South Boston, MA 02127” but it is coming as "SQurh Bosron, MA 02127"

I am using .net 4.5 framework and using aspose dll version 3.5.0.0

Hi Manish,

Thank you for your inquiry and providing sample file.

We have evaluated the attached image at our end. While testing it was found that the image has very low DPI value i.e. 96. Please note that the current implementation of the Aspose.OCR API works well with images having resolution of at least 300 DPI and the accuracy rate tends to decrease by decreasing the resolution. Your provided image has resolution of 96 DPI therefore it will not be possible to get 100% accuracy.

Furthermore the issue has been logged into our system with ID OCR-34250. We are continuously improving recognition quality. Low DPI images will work once issue OCR-34250 is fixed.
