Please refer to the below images to understand about the issue. This is a function used to get image: This is the error window: Its working in python for reference:

Hi @navrkr, sorry I haven't implemented that feature yet. I'd really like to implement it, but I don't have enough time.

At the moment, there are two different workarounds that I can think of:

• The first way is to convert the image to a Nx.Tensor by Evision.Nx.to_nx!(img, Nx.BinaryBackend) (or perhaps you can use :torchx, Evision.Nx.to_nx!(img, Torchx.BinaryBackend)). Then you can use the corresponding function in :nx to achieve the same goal.
• The other way is to use libraries like Image (kipcole9/image), which provides a convenient Image.crop/5 function, and Image support zero-copy between it and Evision.Mat.

I'll leave this issue open until the requested feature is implemented.

Yeah no issues thanks for the great project.

Have you completed implementation of Slicing? Can we expect it to work in next version of Evision?

Yes, we completed and the image is cropped But in that i have small doubt as per ur image again we need to divide each square into separate box At present we are working on detecting the number using tesseract ocr

Please see Evision.Mat.roi in the newly released version.

Thanks alot for your continuous support and update on my own project: It's completed implementation.

Thanks alot bro and update on my project: It's completed implementation. I think it would be appropriate that you take a little time to understand who Cocoa is and be more considered in the way you address her.

Sorry for the inconvenience caused. You are such a beautiful soul.
