LabelImg
LabelImg is a graphical image annotation tool.
It is written in Python and uses Qt for its graphical interface.
The annotation file will be saved as an XML file. The annotation format is PASCAL VOC format, and the format is the same as ImageNet
Build source and use it
- Linux/Ubuntu/Mac
Requires at least Python 2.6 and has been tested with PyQt 4.8.
In order to build the resource and assets, you need to install pyqt4-dev-tools and lxml:
$ sudo apt-get install pyqt4-dev-tools
$ sudo pip install lxml
$ make all
$ ./labelImg.py
Mac requires "$ brew install libxml2" when installing lxml
- Windows
Need to download and setup Python 2.6 or later and PyQt4. Also, you need to install lxml.
Open cmd and go to [labelImg]
$ pyrcc4 -o resources.py resources.qrc
$ python labelImg.py
Download the prebuilt binary directly
http://tzutalin.github.io/labelImg/. However, there are only prebuilt binaries for Windows and Linux because I don't have Mac OS to do that. If someone can help me to write a script to build binary for Mac OS, I will appreciate that.
Usage
After cloning the code, you should run $ make all to generate the resource file.
You can then start annotating by running $ ./labelImg.py. For usage
instructions you can see Here
At the moment annotations are saved as an XML file. The format is PASCAL VOC format, and the format is the same as ImageNet
You can also see ImageNet Utils to download image, create a label text for machine learning, etc
