The increased interest in consumer-grade high dynamic range (HDR) images and videos in recent years has caused a proliferation of HDR deghosting algorithms. Despite numerous proposals; a fast; memory-efficient; and robust algorithm has been difficult to achieve. This paper addresses this problem by leveraging the power of attention and U-Net-based neural representations and using a conservative deghosting strategy. Given two bracketed exposures of a scene; we produce an HDR image that maximally resembles the high exposure where it is well-exposed and fuses aligned information from both exposures otherwise. We evaluate the performance of our algorithm under several different challenging scenarios; using both visual and quantitative results; and show that it matches the state-of-the-art algorithms despite using only two exposures and having significantly lower computational complexity. Furthermore; the parameters of our algorithm greatly simplify deploying its different versions for devices with a variety of computational constraints; including mobile devices. © 1992-2012 IEEE;
