Are you ready to enhance low-light images and explore the world of image restoration with the MIRNet model? Look no further! In this article, we’ll delve into the steps needed to utilize the MIRNet model in TensorFlow.js (TFJS) and guide you through troubleshooting potential issues. Let’s light up those dark images!

A Bit About the Architecture

The MIRNet architecture is akin to a skilled detective—always on the lookout for clues (features) that help solve the mystery of image restoration and enhancement. It employs clever techniques to maintain high-resolution representations while gathering context from low-resolution images.

Key elements of the MIRNet approach include:

• Parallel multi-resolution convolution streams for extracting multi-scale features.
• Information exchange across the multi-resolution streams.
• Spatial and channel attention mechanisms for capturing contextual information.
• Attention-based multi-scale feature aggregation.

In essence, it seamlessly combines the details from multiple resolutions, enhancing the overall image quality.

About the Notebooks

There are three essential Jupyter notebooks in this repository to help you navigate through different aspects of the MIRNet model:

• MIRNet_Saved_Model.ipynb – This notebook demonstrates how to download pre-trained weights and save the MIRNet model.
• MIRNet_TFJS.ipynb – Convert the SavedModel to TFJS format and perform optimizations.
• MIRNet_Inference.ipynb – Run inference on low-light images.

Running the TFJS Model: An Example

Follow these steps to run the MIRNet model on your local machine:

Getting Started

Make sure you have Node.js installed and run the following commands:

git clone git@github.com:Rishit-dagli/MIRNet-TFJS.git
cd MIRNet-TFJS
wget -O .example/model/variables.data-00000-of-00001 https://github.com/Rishit-dagli/MIRNet-TFJS/releases/download/v0.1.0/variables.data-00000-of-00001
cd example
npm install
npm start

Your application should now be accessible at localhost:3000 🚀.

Troubleshooting

Sometimes, the world of programming can be trickier than a maze! Here are a few troubleshooting tips to keep you on track:

• If the app doesn’t start, verify Node.js is correctly installed and you’ve followed the commands closely.
• Check network connectivity. Sometimes the files take longer to download.
• For model testing, navigate to the example folder and run node modeltest.js. Make sure to have a valid input image named input.PNG in the root directory for processing.
