Aiming at the problems of incomplete dehazing of a single image and unnaturalness of the restored image, a multi‐scale single‐image defogging network with local features fused with global features is proposed, using fog and non‐fogging image pairs train the network in a direct end‐to‐end manner. The network is divided into global feature extraction module, multi‐scale feature extraction module and deep fusion module. The global feature extraction module extracts global features that characterize the contour; multi‐scale feature extraction module extracts features at different scales to improve learning accuracy; in the deep fusion module, the convolutional layer extracts the local features that describe the image content, and then the local features and the global features are merged through skip connections. Comparative experiments were carried out on artificially synthesized fog images and real fog images. The experimental results show that the algorithm proposed here can achieve the ideal dehazing effect, and is superior to other comparison algorithms in subjective and objective aspects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
