News

  • [2022-04-20] :fire: PaddleSeg v2.5 is released! More details in Release Notes.
    • Release PP-LiteSeg, a real-time semantic segmentation model. It achieves SOTA trade-off between segmentation accuracy and inference speed. [techical report]
    • Release PP-Matting, a trimap-free image matting model for extremely fine-grained segmentation. It achieves SOTA performance on Composition-1k and Distinctions-646. [techical report]
    • Release MedicalSeg, a newly easy-to-use toolkit for 3D medical image segmentation. It supports the whole process including data preprocessing, model training, and model deployment, and provides the high-accuracy models on lung and spine segmentation.
    • Upgrade the interactive annotation tool EISeg v0.5 with supporting new areas in chest X-Ray, MRI spine, and defect inspection.
    • Add 5 semantic segmentatioin models, including variants of PP-LiteSeg.
  • [2022-01-20] We release PaddleSeg v2.4 with EISeg v0.4, and PP-HumanSeg including open-sourced dataset PP-HumanSeg14K.
  • [2021-10-11] We released PaddleSeg v2.3 with the improved interactive segmentation tool EISeg v0.3, two matting algorithms, and segmentation model compression.

Introduction

PaddleSeg is an end-to-end high-efficent development toolkit for image segmentation based on PaddlePaddle, which helps both developers and researchers in the whole process of designing segmentation models, training models, optimizing performance and inference speed, and deploying models. A lot of well-trained models and various real-world applications in both industry and academia help users conveniently build hands-on experiences in image segmentation.

  • Four segmentation areas: semantic segmentation, interactive segmentation, panoptic segmentation and image matting.


  • Various applications in autonomous driving, medical segmentation, remote sensing, quality inspection, and other scenarios.


Features

  • High-Performance Model: Based on the high-performance backbone trained by semi-supervised label knowledge distillation scheme (SSLD), combined with the state of the art segmentation technology, we provide 80+ high-quality pre-training models, which are better than other open-source implementations.

  • Modular Design: PaddleSeg supports 40+ mainstream segmentation networks, developers can start based on actual application scenarios and assemble diversified training configurations combined with modular design of data enhancement strategies, backbone networks, loss functions and other different components to meet different performance and accuracy requirements.

  • High Efficiency: PaddleSeg provides multi-process asynchronous I/O, multi-card parallel training, evaluation, and other acceleration strategies, combined with the memory optimization function of the PaddlePaddle, which can greatly reduce the training overhead of the segmentation model, all this allowing developers to lower cost and more efficiently train image segmentation model.
