Abstract: Low-light images often suffer from varying degrees of visual degradation. Current methods for recovering image texture details fail to rely on the self-adaptive correlation texture direction of the image itself, which leads the network to be unable to address the local texture characteristics of different images. To address this challenge, we propose a semantic-aware detail adaptive network (SDANet) that fully considers the image detail information. The network divides low-light images into high-frequency and low-frequency parts. Learning different forms of noise through a novel total variation regularization module with adaptive weights ensures that the final high-frequency part adequately integrates the texture information of the image. Simultaneously, a detail-adaptive module is incorporated to restore finer details in the resulting image. SDANet not only effectively suppresses noise in real low-light images while considering texture details but also effectively addresses the degradation of visible information, and it performs better than other state-of-the-art methods.
