LabelImg is now part of the Label Studio community. The popular image annotation tool created by Tzutalin is no longer actively being developed, but you can check out Label Studio, the open source data labeling tool for images, text, hypertext, audio, video and time-series data.

can you give a example,thank you
Can this tool be used in the annotation of gray image? When i use it for the gray image annotation i meet some problem and i can't save the label.
Hello,
The toolbar has disappeared, see below image:
Thanks in advance for your help.

hi, labelImg is an excenlent tool, i am enjoying it.
however ,to most peopel, our hand is not big,hotkey "ctrl+n" is not suitable,whether can you change it ?
Hi , How do I instal the "pyqt4-dev-tools for mac?
Brew install pyqt4-dev-tools raises the error : Error: No available formula with the name "pyqt4-dev-tools"
I am using conda to install everything. Any idea how to get it running for mac?
Hi,
Your tool is awesome now. It is more useful than LabelMe (MIT-CSAIL format).
It will be better if there is a feature to move to an image fast. Such as I am in 1000.jpg, but I want to come back 500.jpg to edit. Or already created 500 images, computer is shutdown or close application, next time?
Now, it seems you must to click back or next 500 times.
Hi Lin:
I have many picture named frame000.jpg to framexxx.jpg in same directory.
When i running labelImg.py and open Dir.
After labeling frame000.jpg i want to next pic but next pic showed isn't frame001.jpg .
Does any solution about it?
I want to create and save the rotation bounding box by record the rotation angle,
Running OSX 10.11, python 2.7, for some reason my environment is missing lxml.
$ python labelImg.py
Traceback (most recent call last):

Any ideas on how to fix this?
Hi @tzutalin ~ This labeling tool is pretty convenient and I like it very much! However, when I click the "open annotation" button, open a previously saved xml file and try to adjust the size and location of the bbox visually, the shape of the bboxes are no longer rectangles. Maybe there is a bug here.
I did this because I wanted to use CNN to pre-label the bboxes so that we can just make some adjustment, which can reduce the workload.
I 'm looking forward to your reply : )
When you click on the "x" button to close the filedock widget, there is no easy way to get it back. Or is there? I didn't see anything in the dropdown menus. There probably should be a toggle under the view menu.
Every time I choose a .jpg file, it pops up an error message:
Error opening file
Make sure /Users/zqsu/Documents/apps/labelImg/demo/demo3.jpg is a valid image file.
I tried my own image and the demo image, all got the same error, but .png and .bmp file work ok.
Here is some information may help:

Thanks :)
Unless the order of the bbox bounds in the xml are:
xmin, ymin, xmax, ymax,
the bbox won't be read in correctly.
The bbox's in original VOC dataset xml's are not guaranteed to have this exact order. Nor should they be.
When I open the labelImg, there is no Box labels window in the right, how can i get the Box labels window?
Hello,
(1) If I annotate 1-channel image, in the xml the will still be 3, do you know where to fix this?
(2) Can you load annotation xml automatically if it's exist for the image?
Thanks!

Hi,
I am using your amazing tool for some picture all with dark background. I was wondering if I can change the background to black. so when I "scroll" through all the images, it won't blink so much.
Thank you!
Hi, I annotated some results but are unreadable by official devkit.
I think the problem is, in the xml file spaces are used instead of tabs (or no space, because I got rid of all spaces by hand and is then readable by VOC devkit).
I wonder if you have a solution for that, thank you.
Thanks for your great work. It's clean and simple.
I want to add some labels such as facial landmarks. Have you any plan ? Or have any suggestion?
after completing make qt5py3 without any warning, do python3 labeling.py,get below:

Hi,
I have already one folder with a database, where the images only contain the object of interest to classify.
Is there exist any fast method to create the xml file to all the images of that folder without selecting the BB on each one of them ? (the object is represented in the entire image)
Thanks
When you load annotations from local xml file and change the position of the points ,the shape will change irregularly.
In "pascal_voc_io.py", function "addShape()",line 121
it should be:
points = [(xmin,ymin), (xmax,ymin), (xmax, ymax), (xmin, ymax)]
rather than:
points = [(xmin,ymin), (xmin,ymax), (xmax, ymax), (xmax, ymin)]
Hi Lin:
The coordinate of the annotation starts from 0 or 1? Thanks!
I think that there is no need to import cv2 module in labelfile.py to get the image shape.
Hi,
I can not run the executable file because of this error:
Segmentation fault (core dumped)
Python 3.5 and PyQT5 and latest Anaconda. Testing on windows 10 with latest stack.
Our Image shape is 7360*4912, I try to open them, but nothing happened. On the other other hand, some small image can be opened success, so I think maybe our image is so bigger then this application allowed. Now, what can I do except resize our Image? who can help me? thx!
I installed requirments software:
brew install libxml2
brew install pyqt5
pip3 install lxml
My pyqt5 verson is 5.8.1
And when I run command:
make qt5py3
It's fine.
But when I run command:
python3 labelImg.py
the program crash. error info as below:

Has anyone written an Python xml parser for using labels and BBoxes?
When I labeled an image, I find there are so many car than other categories.
I want to create a shortcut when I add the car label instead of making double click.
Please help~ Thanks a lot.

An enhancement to support unicode strings would of great help for all who want to assign labels in languages other than English

[1] 4683 abort python3 labelImg.pyHi @tzutalin ,
sometimes we make a dataset for only one label ,such as "dog". However,everytime i create Rectbox, a dialog show to choose a label. For this situation,this operation to choose label is redundant.
In my opinion,this porject could set two modes to fit two situations:one label and multilabel.
In one label mode,when we create a rectbox, the dialog will not show and the label defaultly write into the xml file.
appreciate your excellent work!
Hi,
I am using this tools to distribute it to students so they can annotate images. We have been trying it for a while, in UBUNTU 16.04 machines and it is a very simple and straight forward tool. Perfect for the job.
However, our students claim that they need too many mouse clicks per image, and after evaluating the user interface and usability, we have come to the conclusion that the label image tool would need an improvement in the usability.
At the moment, a whole annotation requires:
Next Image button (1 click) -> Create Box button (1 click)-> actual box creation (2 clicks) -> Select label dialogue (2 fast clicks) -> Save button (1 click) -> Enter (1 touch key) ->
Next Image ... -> ...
That is 7 clicks plus 1 enter key.
Our request (as we dont have the knowledge or resources to accomplish it) would be to reduce it to 2 clicks.
That would be, once the image to work with is on the screen:
That way, we reduce the work form 8 interactions to 2. Obviously, that would be implemented with a mode that user could select (turbo mode), so the user can always go back to the normal mode, to change the label, location..or any other setting.
Well, that is our result of a studding after using it for a while.
Thanks for the good work.
