Welcome to the realm of semantic segmentation—a technique that allows machines to classify each pixel in an image into different object categories. In this article, we will explore how to set up and use the Efficient-Segmentation-Networks project, designed for real-time semantic segmentation models using PyTorch.

Requirements

Before you jump into coding, you need to install some essential prerequisites. Make sure you have PyTorch and Torchvision installed on your system. Use the command below to install all necessary packages:

pip3 install -r requirements.txt

Models

This project features a variety of models for semantic segmentation:

• SQNet: Speeding up Semantic Segmentation for Autonomous Driving Paper
• LinkNet: Efficient Semantic Segmentation Paper
• SegNet: Deep Encoder-Decoder Architecture for Image Segmentation Paper
• UNet: Biomedical Image Segmentation Paper
• AND MANY MORE!

Dataset Setting

This project is tailored for the Cityscapes and CamVid datasets. Your dataset should follow this folder structure:

-- dataset
  -- camvid
    -- train
    -- val
    -- test
  -- cityscapes
    -- leftImg8bit
      -- train
      -- val
      -- test
    -- gtFine
      -- train
      -- val
      -- test

Ensure to download the required datasets by visiting:

• Cityscapes Dataset
• CamVid Dataset

Usage

Now, let’s get into the nitty-gritty of using this repository. First, clone the repository:

git clone https://github.com/xiaoyufenfei/Efficient-Segmentation-Networks
cd Efficient-Segmentation-Networks

The project is designed to run on Python 3 with the following dependencies:

• PyTorch (v1.1 or later)
• Torchvision (v0.3.0)

Training

To start training, here are the commands you can use:

python train.py --help

In this command, replace **train** with your corresponding dataset. Follow similar commands to train on your chosen dataset variations.

Testing, Predicting & Evaluating

For testing and predicting, you can similarly use:

python test.py --help

python predict.py --help

cd tools
python trainID2labelID.py

Understanding the Code: An Analogy

Imagine you’re a chef preparing a complex dish in the kitchen. Each model in this project represents a different recipe. You, the chef (your code), need the right ingredients (data) and tools (functions) to cook every recipe efficiently. Just as a chef would follow specific instructions step-by-step to create a delightful dish, you’ll run your scripts precisely to observe the beautiful pixel segmentation of images.

Troubleshooting

If you encounter issues during installation or execution of scripts, consider these troubleshooting steps:

• Double-check that all required packages are installed without errors.
• Ensure the dataset is correctly structured as mentioned earlier.
• Refer to the specific error messages you receive; they often provide clues to the problems encountered.
• For further assistance, feel free to reach out via email or GitHub issues.
