Semantic labeling made simple
Semi-Supervised Semantic Annotator (S3A)
A highly adaptable tool for both visualizing and generating semantic annotations for generic images.
Most software solutions for semantic (pixel-level) labeling are designed for low-resolution (<10MB) images with fewer than 10 components of interest. Violating either constraint (e.g. using a high-res image or annotating ~1000 components) incur detrimental performance impacts. S3A is designed to combat both these deficiencies. With images up to 150 MB and 2000 components, the tool remains interactive.
A more detailed overview can be found in the project wiki here.
The easiest method for installing
s3a is via
pip after cloning the repository, or directly from pypi:
git clone https://gitlab.com/ficsresearch/s3a pip install -e ./s3a # Or from pypi using "pip install s3a"
Note that a version of OpenCV and Qt binding are required for S3A to work. These can be installed for you with the "turnkey" option:
pip install -e ./s3a[full] # Or "pip install s3a[full]"
Running the App
Running the app is as easy as calling
s3a as a module:
python -m s3a
From here, projects can be created to host groups of related images, or images can be annotated in the default project. Both options are available through the
