Image Polygonal Annotation with Python

Installation | Usage | Tutorial | Examples | Youtube FAQ

## Description Labelme is a graphical image annotation tool inspired by . It is written in Python and uses Qt for its graphical interface. VOC dataset example of instance segmentation. Other examples (semantic segmentation, bbox detection, and classification). Various primitives (polygon, rectangle, circle, line, and point). ## Features - [x] Image annotation for polygon, rectangle, circle, line and point. ([tutorial](examples/tutorial)) - [x] Image flag annotation for classification and cleaning. ([#166](https://github.com/wkentaro/labelme/pull/166)) - [x] Video annotation. ([video annotation](examples/video_annotation)) - [x] GUI customization (predefined labels / flags, auto-saving, label validation, etc). ([#144](https://github.com/wkentaro/labelme/pull/144)) - [x] Exporting VOC-format dataset for semantic/instance segmentation. ([semantic segmentation](examples/semantic_segmentation), [instance segmentation](examples/instance_segmentation)) - [x] Exporting COCO-format dataset for instance segmentation. ([instance segmentation](examples/instance_segmentation)) ## Requirements - Ubuntu / macOS / Windows - Python2 / Python3 - [PyQt4 / PyQt5](http://www.riverbankcomputing.co.uk/software/pyqt/intro) ## Installation There are options: - Platform agnostic installation: [Anaconda](#anaconda), [Docker](#docker) - Platform specific installation: [Ubuntu](#ubuntu), [macOS](#macos), [Windows](#windows) - Pre-build binaries from [the release section](https://github.com/wkentaro/labelme/releases) ### Anaconda You need install [Anaconda](https://www.continuum.io/downloads), then run below: ```bash # python2 conda create --name=labelme python=2.7 source activate labelme # conda install -c conda-forge pyside2 conda install pyqt pip install labelme # if you'd like to use the latest version. run below: # pip install git+https://github.com/wkentaro/labelme.git # python3 conda create --name=labelme python=3.6 source activate labelme # conda install -c conda-forge pyside2 # conda install pyqt # pip install pyqt5 # pyqt5 can be installed via pip on python3 pip install labelme # or you can install everything by conda command # conda install labelme -c conda-forge ``` ### Docker You need install [docker](https://www.docker.com), then run below: ```bash # on macOS socat TCP-LISTEN:6000,reuseaddr,fork UNIX-CLIENT:\"$DISPLAY\" & docker run -it -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=docker.for.mac.host.internal:0 -v $(pwd):/root/workdir wkentaro/labelme # on Linux xhost + docker run -it -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=:0 -v $(pwd):/root/workdir wkentaro/labelme ``` ### Ubuntu ```bash # Ubuntu 14.04 / Ubuntu 16.04 # Python2 # sudo apt-get install python-qt4 # PyQt4 sudo apt-get install python-pyqt5 # PyQt5 sudo pip install labelme # Python3 sudo apt-get install python3-pyqt5 # PyQt5 sudo pip3 install labelme # or install standalone executable from: # https://github.com/wkentaro/labelme/releases ``` ### Ubuntu 19.10+ / Debian (sid) ```bash sudo apt-get install labelme ``` ### macOS ```bash # macOS Sierra brew install pyqt # maybe pyqt5 pip install labelme # both python2/3 should work # or install standalone executable/app from: # https://github.com/wkentaro/labelme/releases ``` ### Windows Install [Anaconda](https://www.continuum.io/downloads), then in an Anaconda Prompt run: ```bash # python3 conda create --name=labelme python=3.6 conda activate labelme pip install labelme ``` ## Usage Run `labelme --help` for detail. The annotations are saved as a [JSON](http://www.json.org/) file. ```bash labelme # just open gui # tutorial (single image example) cd examples/tutorial labelme apc2016_obj3.jpg # specify image file labelme apc2016_obj3.jpg -O apc2016_obj3.json # close window after the save labelme apc2016_obj3.jpg --nodata # not include image data but relative image path in JSON file labelme apc2016_obj3.jpg \ --labels highland_6539_self_stick_notes,mead_index_cards,kong_air_dog_squeakair_tennis_ball # specify label list # semantic segmentation example cd examples/semantic_segmentation labelme data_annotated/ # Open directory to annotate all images in it labelme data_annotated/ --labels labels.txt # specify label list with a file ``` For more advanced usage, please refer to the examples: * [Tutorial (Single Image Example)](examples/tutorial) * [Semantic Segmentation Example](examples/semantic_segmentation) * [Instance Segmentation Example](examples/instance_segmentation) * [Video Annotation Example](examples/video_annotation) ### Command Line Arguments - `--output` specifies the location that annotations will be written to. If the location ends with .json, a single annotation will be written to this file. Only one image can be annotated if a location is specified with .json. If the location does not end with .json, the program will assume it is a directory. Annotations will be stored in this directory with a name that corresponds to the image that the annotation was made on. - The first time you run labelme, it will create a config file in `~/.labelmerc`. You can edit this file and the changes will be applied the next time that you launch labelme. If you would prefer to use a config file from another location, you can specify this file with the `--config` flag. - Without the `--nosortlabels` flag, the program will list labels in alphabetical order. When the program is run with this flag, it will display labels in the order that they are provided. - Flags are assigned to an entire image. [Example](examples/classification) - Labels are assigned to a single polygon.
