About this paper
Simon Raviv, Gal Chechik
VAE-QA introduces an Image Quality Assessment method that utilizes generative representations from a pre-trained Variational Autoencoder, diverging from traditional discriminative approaches. This method shows improved cross-dataset generalization and reduced computational requirements while maintaining competitive performance on standard IQA benchmarks.
Key insights
- Generative models, specifically VAEs, can preserve more visually relevant information for quality assessment compared to discriminative models.
- Utilizing pre-trained VAE encoders for feature extraction enables strong performance and generalization without extensive IQA-specific training.
- Fusing multi-layer features from a VAE's encoder, combined with a simple MLP, can effectively predict image quality.
