- LXML is a lightweight HTML parser even the most popular web scraping framework (Scrapy) is built on the top of LXML, BeautifulSoup is a little bit overloaded with the number of functions exposed to us, it has more functions to use, yes that's right! However in Web Scraping most of the time we use XPath and CSS Selectors to navigate and select.
It is written in Python and uses Qt for its graphical interface.
Annotations are saved as XML files in PASCAL VOC format, the format usedby ImageNet. Besides, it also supports YOLO format
Installation
Build from source
Linux/Ubuntu/Mac requires at least Python2.6 and has been tested with PyQt4.8. However, Python3 or above and PyQt5 are strongly recommended.
Ubuntu Linux
Python 2 + Qt4
Python 3 + Qt5 (Recommended)
macOS
Python 3 + Qt5 (Recommended)
Python 3 Virtualenv (Recommended)
Virtualenv can avoid a lot of the QT / Python version issues
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,PyQt5and install lxml.
Open cmd and go to the labelImg directory
Windows + Anaconda
Download and install Anaconda (Python 3+)
Open the Anaconda Prompt and go to the labelImg directory
Get from PyPI but only python3.0 or above
Use Docker
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 rectbox
- 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 thedata/predefined_classes.txtto load pre-defined classes
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 |
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.
