Realistic Blur Synthesis for Learning Image Deblurring

Training learning-based deblurring methods demands a tre-mendous amount of blurred and sharp image pairs. Unfortunately, existing synthetic datasets are not realistic enough, models trained on them cannot handle real images effectively. While have recently been proposed, they provide limited diversity scenes camera settings, capturing for diverse settings is still challenging. To resolve this, this paper analyzes various factors that introduce differences between images. end, we present RSBlur, novel dataset with the corresponding sequences to enable detailed analysis difference blur. With dataset, reveal effects different in blur generation process. Based analysis, also synthesis pipeline synthesize more We show our can improve performance
