Sign Language Tools

Python library containing various tools for sign language processing.

This project is in an early stage of development. Do not hesitate to contribute!

📖 Documentation: ppoitier.github.io/sign-language-tools

Why?

Why not? It is useful to us, therefore it may be useful to you?

What's included?

• Pose — Extract MediaPipe holistic landmarks from video, connectivity/edge definitions for MediaPipe and OpenPose skeletons, data-augmentation and preprocessing transforms (interpolation, resampling, smoothing, normalization, cropping, ...), and matplotlib plotting for landmarks.
• Video — Decode video files frame by frame, and PyTorch-compatible transforms for video tensors (temporal crop, temporal padding).
• Video Player — A modular, OpenCV-based player to visualize a video alongside its pose landmarks, annotation segments, time series or heatmaps.
• Annotations — Transforms to manipulate segment-based annotations (merging, scaling, converting to frame labels or BIO tags, ...), plus IoU/NMS utilities and a timeline plot.
• Common transforms — Small, data-agnostic building blocks (Compose, Concatenate, Randomize, ...) used to build transform pipelines across the other submodules.

This library pairs with sign-language-data-loading, which loads poses, videos and annotations from a dataset on disk — see the docs for a full example combining the two.

Installation

pip install sign-language-tools

See the installation guide for details and optional dependencies.

What's next?

• More data augmentation and plotting!
• More tools for annotations.
• Tools for image processing.
• To be discussed...
