SIMPLE DIGITS CANNOT BE READ...

[Soroosh Farghadani]

I have tried many ways but still does not work well...

[Yasin Nazlıcan]

Have you tried setting whitelist to only numbers?

[Art Rhyno]

You might be able to use the color of the numbers to your advantage. If you can copy by color and then paste into an image with a margin around edges (see attached), you will probably get acceptable results.

Thanks.

Yeah ,That will work on this example.But unfortunately I dont know what color the numbers will be.

Like this one:

Tools like opencv can be used to try to identify objects in an image and then selecting by color ranges. A lot depends on the variance of the images but some sort of preprocessing to separate out the digits could make a difference.

Yeah,that will work on this example.

But I don't know what color numbers will be.So I can't cut them.
