Abstract

JPEG is the most widely used image compression format, but low quality factors introduce blocking and ringing artifacts that degrade visual quality and hinder computer vision tasks. Existing deep learning methods often require separate models for different compression levels, whereas FBCNN (flexible blind convolutional neural network) handles multiple qualities with a single model but remains limited by ResNet (deep residual learning networks)-based blocks (ResBlocks) in capturing diverse features. To address this, we propose SA-FBCNN (a Spatially Adaptive Flexible Blind deep Convolutional Neural Network) that enhances feature extraction across regions and scales. With lower model complexity, our framework achieves superior quantitative and qualitative JPEG image reconstruction performance.
