Welcome to the world of advanced image processing! In this guide, we will explore MAXIM (Multi-Axis MLP for Image Processing), a groundbreaking architecture introduced at CVPR 2022. This multi-layer perceptron model harnesses the power of deep learning to tackle low-level vision tasks effectively.

Understanding MAXIM: An Analogy

Think of MAXIM as a Swiss Army Knife for image processing. Just as a Swiss Army Knife contains various tools that assist you in different scenarios—screwdrivers, scissors, and can openers—MAXIM is equipped with specialized capabilities for different image tasks: deblurring, denoising, deraining, and more. Instead of relying on a single approach, it employs various mechanisms—like a multi-axis gated MLP—to mix local and global visual cues effectively, making it flexible and efficient.

Getting Started with MAXIM

To begin processing images using MAXIM, you’ll first need to set up the necessary environment and dependencies. Follow these simple steps:

Installation

• Clone the repository from GitHub.
• Navigate into the project directory.
• Install dependencies using the following command:

pip install -r requirements.txt

Importing Pre-Trained Models

MAXIM comes with pre-trained models and exceptional performance metrics. You can find them in the repository under the Results and Pre-trained models section. Make sure to download the models relevant to your task—be it denoising, deblurring, or enhancement—before moving on to executions.

Running Evaluations

Once you have your checkpoints ready, it is time to run the evaluations! The following commands will guide you depending on the task:

Image Denoising

python3 maxim/run_eval.py --task Denoising --ckpt_path $SIDD_CKPT_PATH --input_dir maxim/images/Denoising --output_dir maxim/images/Results --has_target=False

Image Deblurring

python3 maxim/run_eval.py --task Deblurring --ckpt_path $GOPRO_CKPT_PATH --input_dir maxim/images/Deblurring --output_dir maxim/images/Results --has_target=False

Image Deraining

• For Rain Streaks:

python3 maxim/run_eval.py --task Deraining --ckpt_path $RAIN13K_CKPT_PATH --input_dir maxim/images/Deraining --output_dir maxim/images/Results --has_target=False

• For Rain Drops:

python3 maxim/run_eval.py --task Deraining --ckpt_path $RAINDROP_CKPT_PATH --input_dir maxim/images/Deraining --output_dir maxim/images/Results --has_target=False

Image Dehazing

• For Indoor:

python3 maxim/run_eval.py --task Dehazing --ckpt_path $REDISE_INDOOR_CKPT_PATH --input_dir maxim/images/Dehazing --output_dir maxim/images/Results --has_target=False

• For Outdoor:

python3 maxim/run_eval.py --task Dehazing --ckpt_path $REDISE_OUTDOOR_CKPT_PATH --input_dir maxim/images/Dehazing --output_dir maxim/images/Results --has_target=False

Image Enhancement

• For Low-light Enhancement:

python3 maxim/run_eval.py --task Enhancement --ckpt_path $LOL_CKPT_PATH --input_dir maxim/images/Enhancement --output_dir maxim/images/Results --has_target=False

• For Retouching:

python3 maxim/run_eval.py --task Enhancement --ckpt_path $FIVEK_CKPT_PATH --input_dir maxim/images/Enhancement --output_dir maxim/images/Results --has_target=False

Troubleshooting

If you encounter any issues during installation or execution, consider the following troubleshooting tips:

• Ensure that all dependencies are installed correctly using the provided command.
• Verify that your checkpoint paths are correct and that you have the necessary permissions to access these files.
• Check for any updates or issues in the project repository on GitHub.
