mmseg-extension

English | 简体中文

Introduction

mmseg-extension is a comprehensive extension of the MMSegmentation library (version 1.x), designed to provide a more versatile and up-to-date framework for semantic segmentation. This repository consolidates the latest advancements in semantic segmentation by integrating and unifying various models and codes within the MMSegmentation ecosystem. Users benefit from a consistent and streamlined training and testing process, significantly reducing the learning curve and enhancing productivity.

The main branch works with PyTorch 2.0 or higher (we recommend PyTorch 2.3). You can still use PyTorch 1.x, but no testing has been conducted.

Features and Objectives

• MMSegmentation Extension

  This repository extends the capabilities of MMSegmentation 1.x, leveraging its robust framework for semantic segmentation tasks.

• Model Migration

  Models from MMSegmentation 0.x are migrated to be compatible with MMSegmentation 1.x.

• Integration of External Codes

  Codes and models not originally developed with MMSegmentation can be adapted to use MMSegmentation's data loading, training, and validation mechanisms.

• Model Weights Compatibility

  Models trained in their original repositories can be used directly for training and inference in mmseg-extension without the need for retraining.

• Tracking Latest Models

  The repository stays updated with the latest research and models in semantic segmentation.

• Minimal Changes

  The Config file names remain the same as in the original repository, making it easy for developers familiar with the original repository to get started without much hassle.

Addressing Key Issues

• Staying Current with Latest Models

  mmseg-extension addresses the delay in MMSegmentation's inclusion of the latest models by continuously integrating the newest research.

• Standardizing Disparate Codebases

  By providing a unified framework, mmseg-extension solves the problem of inconsistent data loading, training, and validation scripts across different research papers.

• Utilizing Pre-trained Weights

  Ensures compatibility with pre-trained weights from various repositories, enabling seamless model integration without the need for retraining.

Installation and Usage

• Installation: Please refer to get_started.md for installation.

• Usage: Train and test with existing models
