Learning End-to-End Deep Learning Based Image Signal Processing Pipeline Using a Few-Shot Domain Adaptation
Abstract: Nowadays the quality of mobile phone cameras plays one of the most important roles in modern smartphones, as a result, more attention is being paid to the camera Image Signal Processing (ISP) pipeline. The current goal of the scientific community is to develop a neural-based end-to-end pipeline to remove the expensive and exhausting process of classical ISP tuning for each next device. The main drawback of the neural-based approach is the necessity of preparing large-scale datasets each time a new smartphone is designed. In this paper, we address this problem and propose a new method for few-shot domain adaptation of the existing neural ISP to a new domain. We show that it is sufficient to have 10 labeled images of the target domain to achieve state-of-the-art performance on the real camera benchmark datasets. We also provide a comparative analysis of our proposed approach with other existing ISP domain adaptation methods and show that our approach allows us to achieve better results
