l3p-cv / lost Goto Github PK

Hi
I want to know how to perform full lost backup.
Simply backuping Lost Data Folder - folder choosen during installation with sudo permissions does not work.
Steps taken to test if it is working:

1. sudo zip -r backup.zip Lost Data Folder
2. Clean installation of LOST clean_lost folder
3. Creating user with name should_not exist_after_restore
4. LOST shutdown
5. rm -rf clean_lost
6. unzip backup.zip into clean_lost
7. LOST start
8. should_not exist_after_restore still exists and users from backup are not restored

a)Do I need to backup entire docker container along with Lost Data Folder ?
b)Is it somewhat related to docker volume mounting 'rprivate' ?

Many thanks
Konrad Adamczyk

Is your feature request related to a problem? Please describe.
Not directly. When the sim_class parameter is passed with the request_anno function then there is no use for it in the MIA frontend

Describe the solution you'd like
If the requested image is pre-annotated then the image should already be displayed as pre-annotated in the MIA frontend and therefore making it faster in MIA overall

Describe alternatives you've considered
The class should be pre-selected and all images that do not belong are selected in the MIA frontend.

When there are a lot of images to be submitted then nothing happens till the submitting process is finished

Describe the solution you'd like
An indication whether LOST is processing the submit or even a progress bar would be helpful.

Describe alternatives you've considered
A normal loading circle should be enough

When I run docker-compose up it ends up with an error that says:
rabbitmqlost | 2020-01-23 15:18:03.800377 crash_report #{label=>{supervisor,start_error},report=>[{supervisor,{local,net_sup}},{errorContext,start_error},{reason,{"Cookie file /var/lib/rabbitmq/.erlang.cookie must be accessible by owner only",[{auth,init_cookie,0,[{file,"auth.erl"},{line,286}]},{auth,init,1,[{file,"auth.erl"},{line,140}]},{gen_server,init_it,2,[{file,"gen_server.erl"},{line,374}]},{gen_server,init_it,6,[{file,"gen_server.erl"},{line,342}]},{proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"},{line,249}]}]}},{offender,[{pid,undefined},{id,auth},{mfargs,{auth,start_link,[]}},{restart_type,permanent},{shutdown,2000},{child_type,worker}]}]}

...it was deleting before with the DEL key and was received back from the history with CTRL+Z

To Reproduce
Steps to reproduce the behavior:

1. Delete an annotation with the DEL key
2. Receive it back with the keyboard combination CTRL+Z
3. Now try to delete the annotation with the close-X in the right top corner of the annotation
4. Does not work

In my opinion, LabelTree helps to find a class by its superclass.

However, in LOST, you can just choose one between the class and its superclass. I think the exported CSV should contain all the node classes from the root node to the leaf node. In this way, the CSV file can be more rational and sufficient to parse.

remove maxLabel from API

Describe the bug
Sometimes when i switch to a new image to annotate and i want to start with the annotation the point for the polygon is randomly offset to the mouse pointer. It does happen randomly about every ten images. Can not reproduce the bug.
Can be probaply fixed when the position of the mouse pointer is reset for every image.

Expected behavior
The point is set where the mouse pointer is.

Cannot delete pipeline

Expected behavior
Pipeline deleted
When I delete the pipeline，the following page is displayed.

Describe the bug
When using the zoom function of the SIA Editor the view can be moved by click+drag. However the focus of a selected annotation is lost when using it.

To Reproduce
Steps to reproduce the behavior:

1. Open a SIA task
2. zoom into the image using the mouse scroll wheel
3. select or create an annotation and make it active
4. move the image view area by click and drag
5. see the lost focus

Expected behavior
Keeping the focus on the annotation while dragging the view.

Desktop (please complete the following information):

• OS: Win64 x86_64

Describe the bug
When doing SIA the history regarding CTRL+Z contains all previously annotaded images in the session.
This means when pressing CTRL+Z too often you get the history of the previous image into the current image.

To Reproduce

1. Annotate two images
2. When finished with the second press CTRL+Z several times until annotations of the previous images
   is displayed

Expected behavior
Only the annotation history of the current image is displayed to the current image

Different users have different preferences. Some of our annotators reported the wish to have the keyboard shortcuts customizable.

Describe the solution you'd like
As this is user dependend it should be, if implemented, be a user specific configuration

Describe alternatives you've considered
If a user group for an annotation task could agree on a central configuration. It might be an option to have the shortcuts configured during the pipeline design by a configuration file.

Describe the bug
The image area is very constrained by the other UI elements. As a result an image of 1200x700 will be about 900x500 px an a "modern" 1920x1080 dektop. This wasts nearly 80% of the availabel screen area. A smaller laptop screen with the same resolution results in even smaller image area, which makes the tool unusable.

Expected behavior
Maximise the image area to increase the usability. See my proposal image. When moving all control elements to the left or right, making the top info bar foldable there would be enough space to increase the image size significantly.

However element arrangement depends on the used image. For ultra wide images the proposed arrangement would not be optimal. Maybe the UI should calculate differenz arrangements of the control elements (horizontal or vertical) and than select the arrangement with the biggest resulting image area.

Screenshots

Describe the bug
See an example pipeline in screenshot. When I want to start this pipeline the loop gets automatically to finished and the variable self.iteration in the first script node (requestannos.py) is 9.

Expected behavior
The iteration should be 0 not 9 when I start the pipeline.

I have an application where I need to label time-series imagery, I cannot simply convert the images to single images and label those as I am trying to track differences between images in the time series stack (even between pairs of images would be fine for now).

I envision an interface like (https://www.cssscript.com/demo/view-before-after-images-reveal/) where the two images can be compared, with annotation taking place on top of that interface. So far the issue in implementing this seems to be that LOST only fetches a single image from a folder at a time, and the interface only expects a single image.

I am willing to have a go at implementing this, but could you provide some guidance on the best approach and relevant parts of LOST which will need to be updated? I was thinking that instead of relying on flask to fetch the data directly from a folder, perhaps a data loader like interface (as PyTorch etc have) might be the most flexible way to go.

Describe the bug
When i draw the whole polygon twoards the image edge the polygon gets squeezed on the location of edge contact. Means that the points of the polygon do not cross the edge of the image but with further dragging the other points do move and thus the polygon gets squeezed.
Propably the same with bounding boxes and lines.

To Reproduce
Steps to reproduce the behavior:

1. select polygon
2. drag it towards an image border and further

Expected behavior
Not only the point but the whole polygon should not be further moveable when one point edges the images.

Desktop (please complete the following information):

• OS: Windows 10

Describe the bug
When selecting a point of a polygon and pressing the key del at the same time the point gets deleted but the mouse pointer at the same time. Means that the mouse pointer is not visible for the SIA area.

To Reproduce

1. Select a point of a polygon and keep the left mouse button pressed
2. Press del to delete the point
3. => Point disappears aswell as your mouse pointer

Expected behavior
Only the point disappears but not also the mouse pointer

Describe the bug
When only changing the the label of an pre annotated image the changes are not saved.

To Reproduce
Steps to reproduce the behavior:

1. Start a SIA task with prelabel data
2. Go to an image with existing label
3. Select an annotation
4. Change the label
5. Go to next image
6. Go back to previous image
7. See the old label on the changed annotation

This does not happend if the annotation is modified (moved, resized) after the label change.

Expected behavior
The label should be saved after changing it without modifing the annotation

In my annotation case, the new class objects will appear frequently.

In Dataturks, I can go to the backend of the Dataset Project and add the new class. But in LOST, I can't find this feature, so that I have to define a new pipeline. This wastes a lot of time.

Describe the bug
This Bug is only when you have a loop.
When you have in the first iteration images to label in anno task everything works fine.
In the second iteration when there are no images to label the anno task go to 100 but the state is not finished. The Pipeline stucks.

To Reproduce

1. Create a Pipeline with a loop, anno task and script. (screenshot)

Expected behavior
Anno Task state should be fininshed.

Describe the bug
The annotation task logic reserves images for an active user. Those reservations are not released after inactivity. This leads to the need that every user who ever opened the task needs to login at the end and finish the reserved images

To Reproduce
Steps to reproduce the behavior:

1. Create an SIA task for at least two users
2. Login as User 1
3. Open the annotation task
4. Logout User 1
5. Login as User 2
6. Start and try to finish the annotation task
7. one the "last" image click "finish"
8. a pop up apears which tells "not finished" yet
9. task can only be finished by user 1

Expected behavior

• reserved images should be released by using the logout button
• reserved images should be released after a timeout period like the automatic logout
• one active user left should be able to finish the annotation task

It is unnecessary work to always create a new pipeline in the developing work.

Describe the solution you'd like
A simple restart button to restart the pipeline.

Describe the bug
In the database two_d_annos.data stores the annotation data. There are different formats.

1. stores width, height, center x, center y
2. stores width, height, center x, center y and left, right, top, bottom

When exporting the annotations with export_csv.py both formats will be outputted.

Expected behavior
The system should only use one format. From my point of view it should not be format 2. because there are redundant information.

Describe the bug
When deleting an annotation by clicking to the close cross in the right top corner it can not be received back via CTRL+Z keyboard combination

Expected behavior
When deleting the annotation by pressing the DEL key it is saved in the history and can be received back with CTRL+Z

If there are multiple labels for a semantic segmentation task then it is quite cumbersome to handle the annotation task especially for small objects.

Describe the solution you'd like
For this a simple brush tool like in windows paint can be used for a pixel-based annotation. The data can then be saved with run-length encoding

Describe the solution you'd like
The possibility to run LOST as a non-root user as in a user-group in linux

Describe the bug
When copying a script from another pipeline, the update_pipe_project.py updates the wrong entry.

To Reproduce
Steps to reproduce the behavior:

1. Have Pipeline A e.g the example pipeline "no_ai"
2. Create a new pipeline which includes an copy of export_csv.py from "no_ai", let's call it Pipeline B
3. Import Pipeline B with import_pipe_project.py
4. change Pipeline B
5. update Pipeline B with update_pipe_project.py
6. see wrong log output:
   (INFO): Updated script: no_ai.export_csv.py
7. check database: see attached screenshot

Expected behavior
update_pipe_project.py shall only update the selected pipeline.

Let's see this case.

A pipeline has been defined.

But if

• The images in my dataset folder are expanding, but the pipeline annotation progress will not.
• A new class needs to be introduced, but the LabelTree of the pipeline can't be updated.
• I just want to export some already labeled data annotation, but the pipeline makes me have to finish all the annotation task before I export the annotation.

The pipeline is a good character, however, it needs more flexibility.

When i want to view the annotations for a specific image i can do that only by going through all images in the the list until i reach the desired image. So this takes often a lot of unecessary time.

Describe the solution you'd like
It would be nice when i could view an image by the image index/number/imagename.

Describe the bug
When annotating in Google Chrome, I encountered a loss of the label. At that time, I had already annotated a picture. He had more than 100 polygons. When I clicked the next one, I went back to the annotated picture. He has only 50 polygons, and even all polygons are gone.
