Delete images/frames from an existing task

[carlescarmonacalpe]

Hi,

Thank you for this amazing tools, seems really promising. I'd like to suggest a new feature which is to allow to add/delete images/videos from an existing task. From my side it's really common to extend or reduce the dataset size during the development process.

Thank you for you work!

Hi @carlescarmonacalpe ,

Why is it not possible just to create one more annotation task with new images? What is the advantage to update the same task?

[carlescarmonacalpe]

Hi,

The only advantage is that you don't need to modify/join the exported files If you annotate two different tasks and you need to have both annotations together to train a model.

[nmanovic]

Hi @carlescarmonacalpe ,

If you have a good idea how to implement that please send us a PR. Our internal focus is to add stability, introduce analytics, improve UI and implement a couple of semi-automated methods to annotate data. Please let me close the issue for now but if you like implement such functionality don't hesitate to reopen it. In any case I really appreciate your involvements. Thank you very much!

[nmanovic]

Probably it isn't a bad idea to treat an annotation task like a dataset (which can be extended or reduced). It is especially good if we will be able to change status of an annotation task automatically (e.g. done -> annotate). Also a couple of internal customers also requested the feature.

Hi, I used to use vatic and it exported the videos in image format. However on CVAT I can only download the labels, is that right? I've got to convert frames to images on my own?

vcasadei , at the moment you need to prepare data (at least for videos) by yourself. Internally we don't keep original data to save server disk space. When you upload data CVAT does compress images (image_quality parameter when you create an annotation task). Thus 1 frame can weight only 10-100 kilobytes. For example, an original image in png format can be several megabytes. I will submit an issue regarding that. Probably we need one more step in CVAT: prepare a dataset. Thus users can prepare data and after that download them from CVAT as is. If you can help us with such app/feature for CVAT you are welcome.

[nmanovic]

The feature will be implemented only in our new UI. Thus need to move it on v1.0.0 which is expected at the end of the year.

I am facing similar issue where I will have to consolidate/add additional frames with annotation and generate one single JSON file. Is there a way, I can do that?

[davodogster]

Hello @nmanovic and @bsekachev Does it work now? Adding images to an existing task, or merging tasks within a project.

[bsekachev]

@davodogster

No updates on the feature.
Instead of adding images to an existing task, you can move the task to a project and create another task in the project with new images. Finally, you can dump all the annotations for the project, after #3365 will be merged.

As a workaround, you can add to extra images a tag: "extra" for example. And if the annotation file contains this tag, you just ignore the image.

[davodogster]

@bsekachev Awesome, I'm looking forward to using this feature when it has been merged. Thank you

[nmanovic]

@davodogster , it was merged already. Please use the latest development version if you want to test/use the feature.

To close the issue we are waiting ability to mark images/frames as removed in a task.

[davodogster]

@nmanovic Great, thanks. So I need to docker-compose stop, backup my annotations and then clone the latest cvat github repository and then docker-compose again ? Regards, Sam

[nmanovic]

@davodogster , it is the fastest way.

[davodogster]

@nmanovic Hi guys, I just cloned the latest version of cvat and ran docker compose and modified the docker compose file (I notice there were some big changes to the docker compose file) see here:

It deployed successfully but there is no option for exporting a project as a dataset in the "Actions" tab.

Am I doing something wrong?

Hi, please use Export task dataset option in the Actions tab.

Regarding orphans container - it's expected, just follow the docker suggestion and add --remove-orphans once.

[davodogster]

Hi, That is not an option. The only option is delete. That is why I asked the question. Cheers, Sam Get Outlook for iOS<https://aka.ms/o0ukef>

The workaround described above, exporting the labeled data and using those labels on a subset of images, does not work when using COCO annotations, if the images you wish to ignore already contain labels. I don't think the workaround provided above is sufficient for most CVAT users. This is a rather basic functionality, it is perhaps my team's greatest frustration with CVAT.

Is it possible to exec into the PostgreSQL DB and delete annotated images from there?

[domef]

any update on this feature?

[nmanovic]

@domef , it will be available this week.

[bsekachev]

Hi guys, @carlescarmonacalpe @domef

The feature has been finished and implemented in our CVAT fork, here: https://github.com/cvat-ai/cvat

[adamsau]

+1 really need this feature

[nmanovic]

@adamsau , is it something which you are looking for? https://cvat-ai.github.io/cvat/docs/manual/advanced/delete_frame/

[adamsau]

yes thanks a lot!

[bsekachev]

It is possible now, you can update CVAT from develop branch if you want to use the feature.
