1. Project type (Object detection)
2. Windows 10 and Microsoft Edge

I had a few _hand gesture_ datasets with multiple hand classes, all annotated. I needed to clone some images from them into a new dataset, but I noticed in one of them, ~100 of the _right_ class annotated images did not appear. I therefore cloned the _right_ images from another one of my datasets, which had the correct ~200 amount. I cloned all the images of forward, left, and right into a dataset called _nano hand gestures_. I generated an augmented dataset and noticed that many _right_ class images lost their annotation and also noticed that about 100 of the _right_ images did not show up in the Dataset tab, showing that this bug happened again. I replicated this bug again when I created _nano hand gestures 2_ to try to stop the 100 images disappearing:

I believe that this may be the reason why a model I trained on one of the original _hand gesture_ datasets had really bad accuracy on the _right_ class. Why does this happen? I would provide more images but can’t because I’m a new user.

Thank you in advance.

Here’s an image demonstrating that the annotations got lost

Hi @1ucas

Sorry to hear you’re having issues. As I understand, you’re having issues with annotations not showing up. Cloning images on Universe has two options: Importing the images & annotations, or just the images.

Can you confirm that when you cloned the images, you selected the option to clone both the image and annotations?

I’ll check on the image not being marked as null, but being included in the set.

Thank you for your quick reply.

Yes, I used _Import Images and Annotations_. I tried it again on another set _nano hand gestures - cloning for bug test_ by cloning the annotated right hands from _old hand gestures 3_, but many just lost their annotations the same way as previously.

I think the “hiding” of the right hand images from not showing as _right_ nor showing as _Marked Null_ has to do with the loss of annotations, but it’s weird because when they lose their annotations, they should be marked as _Marked Null_.
