Is there an api that puts the cropped image to the desired location of the original image?

Hello. I am a graduate student studying medical imaging.

Is there an api that puts the cropped image to the desired location of the original image?

3D patches were extracted from brain MRI through "SpatialCrop".
I did data augmentation on the 3D patch through gan, and I want to overwrite the generated patch at the desired location of the original brain MRI.
Is there an API that does that?

Thank you.

It's fairly easy to replace a portion of an image with another. You would do this with: image[start_c:end_c, start_h:end_h, start_w:end_w, start_d:end_d] = inferred_image.

You mention that you're using SpatialCrop, which implies that you know the parameters of the cropped region, so can determine start_c, end_c, etc. However, you also mentioned that you're doing this as data augmentation, which might mean that you're doing some random cropping (e.g., RandSpatialCrop). In this case, you should be able to determined the cropping parameters by inspecting the image_transforms key in your data (assuming you are using dictionary transforms).

Let me know if this doesn't quite answer your question.
