+title: MAXIM models
+description: New models based on the MAXIM architecture released
+slug: maxim-models
+authors: kscott
+tags: [announcement]
+hide_table_of_contents: false
+---
+
+I've released Tensorflow.js ports of the [MAXIM family of models](https://arxiv.org/abs/2201.02973), supporting the ability to deblur, denoise, derain, dehaze, retouch, and low-light enhance images.
+
+<!--truncate-->
+
+## Motivation
+
+UpscalerJS was originally created in 2020 with a primary goal of upscaling images. So far, all the models have been exclusively focused on super resolution.
+
+Today I'm releasing a new family of MAXIM models for UpscalerJS that enable a variety of new image enhancement techniques, including:
+
+- [Deblurring](https://upscalerjs.com/models/available/maxim-deblurring)
+- [Denoising](https://upscalerjs.com/models/available/maxim-denoising)
+- [Deraining](https://upscalerjs.com/models/available/maxim-deraining)
+- Dehazing (both [indoor](https://upscalerjs.com/models/available/maxim-dehazing-indoor) and [outdoor](https://upscalerjs.com/models/available/maxim-dehazing-outdoor))
+- [Low Light Enhancement](https://upscalerjs.com/models/available/maxim-enhancement)
+- [Retouching](https://upscalerjs.com/models/available/maxim-retouching)
+
+These models are available in Javascript via UpscalerJS, and run in both the browser and Node.js.
+
+## MAXIM
+
+MAXIM is the architecture at the heart of these new models.
+
+The MAXIM paper ([MAXIM: Multi-Axis MLP for Image Processing](https://arxiv.org/abs/2201.02973)) was published in 2022, and was nominated as one of the best papers at CVPR 2022. The MAXIM architecture is capable, via training, of supporting a variety of image enhancement tasks. It's also an efficient architecture, making it particularly appealing for JavaScript applications.
+
+> We present a multi-axis MLP based architecture called MAXIM, that can serve as an efficient and flexible general-purpose vision backbone for image processing tasks ... Our extensive experimental results show that the proposed MAXIM model achieves state-of-the-art performance on more than ten benchmarks across a range of image processing tasks, including denoising, deblurring, deraining, dehazing, and enhancement while requiring fewer or comparable numbers of parameters and FLOPs than competitive models. 
+
+Google Research [published an implementation in Jax](https://github.com/google-research/maxim), and additional ports were made available in [Tensorflow](https://github.com/sayakpaul/maxim-tf) and [Pytorch](https://github.com/vztu/maxim-pytorch/tree/main/maxim_pytorch).
+
+## Getting Started
+
+You can run MAXIM models in the browser or Node.js. To get started, install your desired model:
+
+```bash
+npm install @upscalerjs/maxim-deblurring
+```
+
+And provide the model as an argument to UpscalerJS:
+
+```javascript
+import model from '@upscalerjs/maxim-deblurring'
+const upscaler = new Upscaler({
+  model,
+})
+```
+
+For model-specific instructions, [check out the specific model page](/models) you're interested in.

+
+## Technical Information
+
+My original attempts at getting this working leveraged both the [Jax repo](https://github.com/google-research/maxim/) as well as the [Tensorflow port](https://github.com/sayakpaul/maxim-tf/tree/main). The ported Jax model exhibited close-to-identical fidelity with its Python implementation, but the Tensorflow port was far more performant in the browser, albiet with noticeably inferior fidelity.
+
+Both implementations originally required fixed size inputs in order to port to Tensorflow.js. Fixed size inputs require chunking images, which can break models that rely on a holisitic view of the image, specifically the Dehazing models, Enhancement model, and Retouching model. (For samples of the artifacting this produces and a longer discussion, [see this Github issue](https://github.com/thekevinscott/UpscalerJS/issues/913).)
+
+I modified the MAXIM Jax code to support dynamic image input sizes, [and opened a PR here](https://github.com/google-research/maxim/pull/41). [This PR is also integrated in my fork of the MAXIM code](https://github.com/thekevinscott/maxim).
+
+(There is also an [open PR against the Tensorflow repo exploring dynamic sizes](https://github.com/sayakpaul/maxim-tf/pull/24); when it gets merged, I'll explore porting it to Tensorflow.js as well.) 
+
+If you'd like to check out the Tensorflow implementation port (noticeably faster, noticeably worse inference, and a fixed size input) these models are available under the `maxim-experiments` repo in the UpscalerJS repo. Clone the repo, pull the models (`dvc pull`) and you'll see fixed-input models of `64` and `256` pixel sizes respectively for each task.
+
+## Converting the files yourself
+
+If you'd like to convert the original Jax or Tensorflow model files yourself, instructions are [in these Jupyter notebooks](https://github.com/upscalerjs/maxim). Feel free to open an issue on Github if you run into issues or questions.
+
+----
+
+The past few years have seen an explosion of innovation in the image enhancement space, and I hope to continue bringing the latest innovations to Javascript. MAXIM is a first step towards enabling Javascript-based image enhancement tasks beyond super resolution in UpscalerJS.
+
+If you have particular models you'd like to see available via UpscalerJS, [let me know in Github](https://github.com/thekevinscott/UpscalerJS/discussions/new?category=ideas). If you use MAXIM in your work, [I'd love to hear about it](https://github.com/thekevinscott/UpscalerJS/discussions/new?category=show-and-tell)! And if you run into questions or find bugs, [please open a bug report](https://github.com/thekevinscott/UpscalerJS/issues/new?assignees=thekevinscott&labels=&projects=&template=bug_report.md&title=).
