'NSInternalInconsistencyException', reason: 'Invalid parameter not satisfying: task.downloadURL' about ocrsdk.com

[Dmitry-Me]

It looks like task processing failed and its state is not Completed but perhaps ProcessingFailed or some other state. If this happens then didStartElement in Task.m doesn't set downloadURL because there's nothing to set. The code you cite doesn't handle this case properly. The right behavior would be to check task.status and proceed depending on its value.

Hi, Dmitry
Thank you very much for your reply.
You are right. The task processing failed because the app ID I used had no balance.
So I used another app ID with some balance pages, and your code works very well.

By the way do you happen to know if ABBYY Cloud SDK supports OCR of handwritten documents as well?
I really appreciate your help, and wish you best of luck in the new year.
Thank you.

It supports "handprinted" text - text written by hand one character at a time. http://ocrsdk.com/documentation/specifications/text-types/ "Handprinted" text is how various forms are filled in by hand - you have a grid and write one character per grid cell.

[youquanli]

Thank you for your quick consideration.
I'm trying to recognize images of handwritten text and I've tried with that option.
Unfortunately, it doesn't work so well, so I'm afraid I have to find another service.
Now I've been looking for a good one for over 2 weeks, but no luck.
I should be grateful if you could recommend one if any.
Thank you.

[Dmitry-Me]

What's your scenario? Do you have predefined forms with known layout?

[Dmitry-Me]

The issue with overly optimistic handling of finished tasks should have been fixed with this commit e0fb87d

[youquanli]

I'm trying to recognize the following sample image, but I couldn't get result. Thanks.

[Dmitry-Me]

What's the problem exactly? What do you do and what do you get that doesn't meet your expectation?

[youquanli]

I've uploaded the above image and got:(Now I'm using the sample project with app id and secret replaced)

[Dmitry-Me]

Which API method (and with which parameters) do you use to initiate processing?

[youquanli]

I tried with processImage and processTextField methods.

[Dmitry-Me]

processTextField should work. With this image the problem is most likely because of high amounts of noise and low image contrast.

[youquanli]

That's right. I think I have to do preprocessing.
Thank you for your help.

[Dmitry-Me]

If this is a photo then you could improve image quality greatly by using proper lighting.
