fbcnn¶

Use Case and High-Level Description¶

The fbcnn model is a flexible blind convolutional neural network to remove JPEG artifacts. Model based on “Towards Flexible Blind JPEG Artifacts Removal” paper. It was implemented in PyTorch* framework. Model works with color jpeg images. For details about this model and other jpeg artifacts removal models (for grayscale images and double jpeg restoration), check out the “Towards Flexible Blind JPEG Artifacts Removal (FBCNN, ICCV 2021)”.
