labelimg's Introduction

Label Studio is a modern, multi-modal data annotation tool =======

LabelImg, the popular image annotation tool created by Tzutalin with the help of dozens contributors, is no longer actively being developed and has become part of the Label Studio community. Check out Label Studio, the most flexible open source data labeling tool for images, text, hypertext, audio, video and time-series data. Install Label Studio and join the slack community to get started.

About LabelImg ========

LabelImg is a graphical image annotation tool.

It is written in Python and uses Qt for its graphical interface.

Annotations are saved as XML files in PASCAL VOC format, the format used by ImageNet. Besides, it also supports YOLO and CreateML formats.

Installation

Get from PyPI but only python3.0 or above

This is the simplest (one-command) install method on modern Linux distributions such as Ubuntu and Fedora.

pip3 install labelImg
labelImg
labelImg [IMAGE_PATH] [PRE-DEFINED CLASS FILE]

Build from source

Linux/Ubuntu/Mac requires at least Python 2.6 and has been tested with PyQt 4.8. However, Python 3 or above and PyQt5 are strongly recommended.

Ubuntu Linux

Python 3 + Qt5

sudo apt-get install pyqt5-dev-tools
sudo pip3 install -r requirements/requirements-linux-python3.txt
make qt5py3
python3 labelImg.py
python3 labelImg.py [IMAGE_PATH] [PRE-DEFINED CLASS FILE]

macOS

Python 3 + Qt5

brew install qt  # Install qt-5.x.x by Homebrew
brew install libxml2

or using pip

pip3 install pyqt5 lxml # Install qt and lxml by pip

make qt5py3
python3 labelImg.py
python3 labelImg.py [IMAGE_PATH] [PRE-DEFINED CLASS FILE]

Python 3 Virtualenv (Recommended)

Virtualenv can avoid a lot of the QT / Python version issues

brew install python3
pip3 install pipenv
pipenv run pip install pyqt5==5.15.2 lxml
pipenv run make qt5py3
pipenv run python3 labelImg.py
[Optional] rm -rf build dist; pipenv run python setup.py py2app -A;mv "dist/labelImg.app" /Applications

Note: The Last command gives you a nice .app file with a new SVG Icon in your /Applications folder. You can consider using the script: build-tools/build-for-macos.sh

Windows

Install Python, PyQt5 and install lxml.

Open cmd and go to the labelImg directory

pyrcc4 -o libs/resources.py resources.qrc
For pyqt5, pyrcc5 -o libs/resources.py resources.qrc

python labelImg.py
python labelImg.py [IMAGE_PATH] [PRE-DEFINED CLASS FILE]

If you want to package it into a separate EXE file

Install pyinstaller and execute:

pip install pyinstaller
pyinstaller --hidden-import=pyqt5 --hidden-import=lxml -F -n "labelImg" -c labelImg.py -p ./libs -p ./

Windows + Anaconda

Download and install Anaconda (Python 3+)

Open the Anaconda Prompt and go to the labelImg directory

conda install pyqt=5
conda install -c anaconda lxml
pyrcc5 -o libs/resources.py resources.qrc
python labelImg.py
python labelImg.py [IMAGE_PATH] [PRE-DEFINED CLASS FILE]

Use Docker

docker run -it \
--user $(id -u) \
-e DISPLAY=unix$DISPLAY \
--workdir=$(pwd) \
--volume="/home/$USER:/home/$USER" \
--volume="/etc/group:/etc/group:ro" \
--volume="/etc/passwd:/etc/passwd:ro" \
--volume="/etc/shadow:/etc/shadow:ro" \
--volume="/etc/sudoers.d:/etc/sudoers.d:ro" \
-v /tmp/.X11-unix:/tmp/.X11-unix \
tzutalin/py2qt4

make qt4py2;./labelImg.py

You can pull the image which has all of the installed and required dependencies. Watch a demo video

Usage

Steps (PascalVOC)

Build and launch using the instructions above.
Click 'Change default saved annotation folder' in Menu/File
Click 'Open Dir'
Click 'Create RectBox'
Click and release left mouse to select a region to annotate the rect box
You can use right mouse to drag the rect box to copy or move it

The annotation will be saved to the folder you specify.

You can refer to the below hotkeys to speed up your workflow.

Steps (YOLO)

In data/predefined_classes.txt define the list of classes that will be used for your training.
Build and launch using the instructions above.
Right below "Save" button in the toolbar, click "PascalVOC" button to switch to YOLO format.
You may use Open/OpenDIR to process single or multiple images. When finished with a single image, click save.

A txt file of YOLO format will be saved in the same folder as your image with same name. A file named "classes.txt" is saved to that folder too. "classes.txt" defines the list of class names that your YOLO label refers to.

Note:

Your label list shall not change in the middle of processing a list of images. When you save an image, classes.txt will also get updated, while previous annotations will not be updated.
You shouldn't use "default class" function when saving to YOLO format, it will not be referred.
When saving as YOLO format, "difficult" flag is discarded.

Create pre-defined classes

You can edit the data/predefined_classes.txt to load pre-defined classes

Annotation visualization

Copy the existing lables file to same folder with the images. The labels file name must be same with image file name.
Click File and choose 'Open Dir' then Open the image folder.
Select image in File List, it will appear the bounding box and label for all objects in that image.

(Choose Display Labels mode in View to show/hide lablels)

Hotkeys

Ctrl + u	Load all of the images from a directory
Ctrl + r	Change the default annotation target dir
Ctrl + s	Save
Ctrl + d	Copy the current label and rect box
Ctrl + Shift + d	Delete the current image
Space	Flag the current image as verified
w	Create a rect box
d	Next image
a	Previous image
del	Delete the selected rect box
Ctrl++	Zoom in
Ctrl--	Zoom out
↑→↓←	Keyboard arrows to move selected rect box

Verify Image:

When pressing space, the user can flag the image as verified, a green background will appear. This is used when creating a dataset automatically, the user can then through all the pictures and flag them instead of annotate them.

Difficult:

The difficult field is set to 1 indicates that the object has been annotated as "difficult", for example, an object which is clearly visible but difficult to recognize without substantial use of context. According to your deep neural network implementation, you can include or exclude difficult objects during training.

How to reset the settings

In case there are issues with loading the classes, you can either:

From the top menu of the labelimg click on Menu/File/Reset All
Remove the .labelImgSettings.pkl from your home directory. In Linux and Mac you can do:

rm ~/.labelImgSettings.pkl

Can not open HD Photo

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!

make: *** No rule to make target `Makefile'. Stop.

when I do make all, I am getting message:
make: *** No rule to make target `Makefile'. Stop.

It also delete all files in dir.

can not save xml file on win10

when I have finished annotation the image that I can't save xml files in window 10.when I tick the button to save the xml file to my folder .I can find nothing in my computer. I have installed python2.7, pyQt4, numpy, and lxml, PIL on my computer.

Question / Fast Annotation

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

How to change GUI color

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!

Needs updates

Python 3.5 and PyQT5 and latest Anaconda. Testing on windows 10 with latest stack.

how to create and save rotation bounding box?

I want to create and save the rotation bounding box by record the rotation angle,

User interface quicker. Too many clicks per annotation.

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:

1st click: Selecting the first corner of bounding box (xmin, ymin)
2nd click: Selecting the second corner of bounding box (xmax, ymax), select automatically the label (the previous selected one), save it with the recommended name in the previous location(name of image.xml) with no dialogue box, then go to next image and activate the Create box tool, signaling the image as a non edited one (not to confuse the operator), as after half an hour, the operator start to get confused with the images, so it would be perfect a visual signal to see if the image is being edited.

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.

Can't reopen filedock after close

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.

I am using conda to install everything. Any idea how to get it running for mac?

bbox mins and maxs don't line up when reading image from original VOC dataset.

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.

How to add shortcut when I create a label？

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.

There is some thing wrong with function addShape in "pascal_voc_io.py" and I've modefied it.

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)]

Can't open annotations with more than 6 boxes

Fast move feature.

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.

Enhancement Request- Support for Unicode labels

I wanted to assign unicode strings to my bounding boxes. I can enter my strings to the text box in UI and is being rendered correctly. But upon save it throws an error.

Traceback (most recent call last):
  File "./labelImg.py", line 945, in saveFile
    else self.saveFileDialog())
  File "./labelImg.py", line 968, in _saveFile

    name.text = str(each_object['name'])
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-10: ordinal not in range(128)

I tried to fix it by the way the string is encoded before being written to xml. But the best I could get was a sequence of unicode points like this written to the xml in place of the actual unicode string.
<name>വിക്കിപീഡിയ</name>

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

result xml not readable by devkit

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.

whether can you simplify choose label operation when we only have one label situation？

Hi @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!

No module named lxml

Running OSX 10.11, python 2.7, for some reason my environment is missing lxml.

rm cv2 module

I think that there is no need to import cv2 module in labelfile.py to get the image shape.

Why there is no Box labels in my labelImg

When I open the labelImg, there is no Box labels window in the right, how can i get the Box labels window?

There seems to be a bug when opening the annotation file and visually adjust the size and location of the previously labeled bboxes？

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 : )
