New framework enables reference-free evaluation of camera ISP pipelines

Researchers have developed a novel reference-free framework for evaluating image signal processing (ISP) pipelines in cameras. This method estimates full-reference image quality metrics like PSNR, SSIM, and LPIPS by predicting a proxy reference image from a processed sRGB image and its ISO metadata. The framework demonstrates effectiveness in adapting to changes in ISP components through lightweight LoRA fine-tuning and outperforms existing blind IQA methods in estimating metric values and rankings.
