Why the OCR predicts two similar images differently

Hello all.

I am attaching two similar images (just different in the pixels number - one is cropped while the odeth isn't). Why the following code works differently between both of them?

ocr((imread('test1.jpg')),'TextLayout','Block')
ocr((imread('test3.jpg')),'TextLayout','Block')

Best, Ahmad

@Walter Roberson, Any suggestions here? Thanks!
