Due to the absorption and scattering effect of the atmosphere, it is difficult to extract effective target information from the image sensor under severe hazy conditions. We propose an end-to-end convolutional neural network designed to solve the problem of image restoration in scattering imaging. And we explicitly consider the atmospheric scattering model of the hazing process in the network design. The encoder and decoder modules are used for feature extraction, and the pyramid pooling network is used to preserve the multi-scale features of the image. The attention mechanism is introduced in the network. Encoder module is adopted for BoTNet that incorporates self-attention for multiple computer vision tasks. Due to the lack of real hazy images, we collected scattered images under low visibility conditions and corresponding haze-free images. We examine the proposed method by the challenge datasets, the experiments demonstrate that the proposed method can effectively extract and recover the feature information of the target. The results show that, compared with the traditional signal processing method, our model achieves significant practical performance gains and restores the detailed information of the image.
