An app for removing compression and noise from photos

This is not another "AI upscaler" but a compression artifact remover and denoiser using public models such as FBCNN and SCUNet

features:

• Remove compression artifacts
• Denoise
• Before/after view
• Fully offline

models:

You can download models here

examples:

Check out examples to get an idea of what DeJPEG can be used for

limitations:

• Processed locally, a fast device is recommended
• Only standard image formats supported

desktop support:

chaiNNer is a cross-platform image/model utility, which should work well with these models

For FBCNN, which chaiNNer does support but in a limited fashion, install this custom node and use the original PyTorch models, not the mobile onnx.

building

standard gradle build process

disclaimer:

I am by no means a professional developer and only do this in my spare time, the code is not perfect and quite janky.

This is a GUI for a select amount of 1x ONNX processing models, used under their respective licenses (Apache 2.0)

You are welcome to embed parts of this app in your own project as long as it remains free as in beer, abides to the GPLv3 license, and credit has been given

Credits to @adrianerrea for a starting point, FBCNN and SCUNet creators plus all other model owners.

DeJPEG is not affiliated or related with Topaz DEJPEG or any other similarly named software/project. Although I've wondered if the term 'JPEG' is copyrighted/trademarked due to it literally being the acronym for Joint Photographic Experts Group, for this reason I might need to change the app's name if legal issues start to occur.
