@bsekachev, @azhavoro, could you look at the PR, please?

@bsekachev, @azhavoro, could you look at the PR, please?

@ActiveChooN It looks like the deleted_frames field is not kept in a task's backup/restore archive. Most likely it will be enough to add this field here https://github.com/openvinotoolkit/cvat/blob/develop/cvat/apps/engine/backup.py#L106

[ActiveChooN]

@azhavoro, fixed.

• I believe the setting "show deleted frames" is bettter to be in player section

• All frames are grayscale:

• If I give a direct command to go to a deleted frame, it goes to non-deleted neighborhood, I am not sure it is expected behaviour.

• If I remove the latest frame of a job, it is not removed visually (icon to remove is not changed, grayscale effect is not visible). After updating a page, remove effects are applied.

• Looks like removing/restoring frames does not update database field updated_date of a task, so, when I dump annotations, then remove a frame, and dump annotations again, I get cached version of dump where the frame is not removed. Maybe the same bug exists for projects likewise.

• When I try to export a dataset for a task with one removed image (where some annotations exist, I get following error)

• According to minutes from our latest discussion:

  • What happens if all frames in job are deleted. There will be a message about empty job instead of frame and inactivated annotation view It is not implemented, as I can see.

Done.

• All frames are grayscale:

Done.

If I give a direct command to go to a deleted frame, it goes to a non-deleted neighborhood, I am not sure it is expected behavior.

If you want to navigate through it's better to turn on the "Show deleted frames" option. If not, only navigation through non-deleted frames is available.

• If I remove the latest frame of a job, it is not removed visually (icon to remove is not changed, grayscale effect is not visible). After updating a page, remove effects are applied.

Fixed.

• When I try to export a dataset for a task with one removed image (where some annotations exist, I get following error)

Fixed.

• What happens if all frames in job are deleted.

I thought another time and preferred to show deleted frames if no non-deleted frames are available because the state of the empty job differs from the state when all frames are deleted. And also it makes look of all deleting pipeline more consistent, I guess.

[bsekachev]

If you want to navigate through it's better to turn on the "Show deleted frames" option. If not, only navigation through non-deleted frames is available.

It does not satisfy discussed HLD. And I actually do not think it is expected behaviour for users because they even does not know about this checkbox exists.

[ActiveChooN]

@bsekachev, @nmanovic, PR is mostly done, the only issue with interpolating on the client. If the job has keyframes on deleted frames there can be an annotation shift on nearby frames, if those keyframes are ignored in the interpolation process. That issue is not related to interpolation on the server, because in that situation keyframes are deleted completely.

[bsekachev]

Update overlay filter for deleted frames for more clarity;

As far as I remember for deleted frames we discussed something like trash icon.. What do you think?

I found one issue with step forward/backward navigation: If I have deleted frames 0,1,2 and go to the 3rd frame, press backward, backward, backward I visite frames 2,1,0. If I press back, back, back navigation don't change frame (as expected). Need to check the same case when we have deleted frames latest, latest - 1, latest - 2 and go forward.

Add keyframes at the edges of the deleted interval to reduce annotations shift;

I have a polygon track with three keyframes (0, 10, 11 [outside keyframe]), I dump data as CVAT for video and don not see any edge keyframes on frame 1. Did I do something wrong?

[bsekachev]

If the job has keyframes on deleted frames there can be an annotation shift on nearby frames, if those keyframes are ignored in the interpolation process.

As far as I remember we discussed that we can use information about keyframes on removed frames during interpolation on client, but maybe it is not exactly true as I think now.

Maybe better idea is to add keyframes automatically around frame that has been just removed? For example if we remove frame N, we add for all tracks (on frame N) keyframes on frames N-1 (if exists, and the track is presented there, and not keyframe so far), and N+1 (if exists and the track is presented there, and not keyframe so far), keeping position as is. It corresponds to the server solution, and not break any data somehow (maybe it a bit less convenient when we want to restore removed frame, but I am not sure it is really often scenario).

@bsekachev , if a user delete a keyframe, does CVAT add something after and before for the frame?

[bsekachev]

BTW, are we planning to do something with filters in this PR? (search deleted frames, navigation redesign, etc.?) considering Andrey's feedback https://github.com/openvinotoolkit/cvat/issues/3075#issuecomment-1047589431?

[bsekachev]

If I have a track with all keyframes on deleted frames (including outside keyframes), I get dataset export error: List index out of range.

[bsekachev]

One more related issue with interpolation (inconsistency). If I remove a frame with outside track keyframe, on UI I don't see the track anymore (as expected) on the following frames, but in dumped file the track lasts till the end of a video.

[nmanovic]

@ActiveChooN , need to resolve conflicts

[klakhov]

Tried this patch: deleting frames, import/export with deleted frames works fine for me. Didn't meet any issues

@ActiveChooN , after I delete an image and restore it, some frames have unexpected white boundaries. It looks like wrong meta information is used to calculate the size of images on the canvas.

[nmanovic]

@ActiveChooN , I believe we decided to draw "trash bin" for deleted images instead of strips. Could you please clarify?

@ActiveChooN , I don't think we need to show the dialog, if we don't have any annotations on the frame

[nmanovic]

[nmanovic]

@ActiveChooN , after I click once on "delete" button, I got the following requests below. It looks like we do requests twice. Why? Also I will prefer don't send any requests to the server and do that explicitly only after "save" button is pressed. It will correspond to the current behaviour.

@nmanovic, can you please share task backup for issue reproduction?

[ActiveChooN]

@ActiveChooN , I don't think we need to show the dialog, if we don't have any annotations on the frame.

In my opinion, every major delete action should be wrapped into dialog to prevent missclicking

Please use https://public.roboflow.com/object-detection/oxford-pets to reproduce. It is important just have images with different sizes. Let me know if you cannot reproduce.

Only in case it has strong consequences (e.g., remove annotations). Also I don't like that we move to the next image automatically. Need to think twice about the behaviors.

[ActiveChooN]

Let me know if you cannot reproduce.

Should be there special steps to reproduce the issue?

[ActiveChooN]

@nmanovic

Also I don't like that we move to the next image automatically. Need to think twice about the behaviors.

Moving to the next frame is only working if the "Show deleted frames" option is disabled.

[nmanovic]

@ActiveChooN , automatic annotation is running on all frames, even deleted.

[nmanovic]

@ActiveChooN , could you please check tests? Are they hanging?

[nmanovic]

@ActiveChooN , if I delete a frame with annotations and after that restore it, I still can see annotations. But if I go to the next frame and return back, it is disappeared. Could you please check?

[nmanovic]

@ActiveChooN , I see some strange artifacts for trash bin. Is it a standard picture?

[nmanovic]

@ActiveChooN , do we have any shortcuts to delete a frame quickly? For now it is necessary for every deleted frame click twice using mouse. I will have two shortcuts with and without confirmation and show them in hints.

[nmanovic]

@ActiveChooN , don't like that in meta information we have a separate array for deleted frames. Do you see any ways to have "is_deleted" attribute as a part of information about a frame?

[nmanovic]

@ActiveChooN , why do we have a warning when we delete a frame without annotation but don't have a warning when we restore the frame?

[nmanovic]

@ActiveChooN , found a problem with tracks. Let's draw a track with key frames on 0, 10, 20 frames. If you delete the frame 0, the track will be removed completely. It tells me that the idea to delete annotations could be wrong and dangerous. Need to think one more time about that. Only in CVAT format we dump key frames only. It looks like it is the main problem.

[ActiveChooN]

@nmanovic,

@ActiveChooN , don't like that in meta information we have a separate array for deleted frames. Do you see any ways to have "is_deleted" attribute as a part of information about a frame?

We have video meta without object per frame information, so is_deleted key is not applicable in that case.

@ActiveChooN , I see some strange artifacts for trash bin. Is it a standard picture?

It's the default delete icon in antd, fixed it manually.

[violino22]

"It will be possible to mark a frame as deleted after the PR is merged" What is "PR is merged"?

[nmanovic]

The pull request (PR) should be merged into develop branch and after that we should publish a release.

[violino22]

Запрос на включение (PR) должен быть объединен с веткой разработки, после чего мы должны опубликовать релиз.

Я просто наёмный работник))) Я не хочу заморачиваться. Я просто хочу клацать на кнопочки, чтоб удалялись ненужные файлы из задачи, это возможно?)))

[nmanovic]

Yes, I understand that. In this case just wait. I hope in next release the feature should be available.

[FrankUSC]

@nmanovic This is a very useful feature, do we have an ETA when will it be released? Thank you!

[nmanovic]

@FrankUSC , it will be release this month.
