MFBF-Net: dehazing network based on multifrequency branch fusion

Image dehazing technology is a hot topic in the fields of image processing and computer vision, aiming to obtain details and texture features of the original scene from foggy images, and then obtain clear and fog free images. Most of the existing research methods are suitable for tasks in low fog scenarios. As the fog concentration increases, the image reconstruction quality of the algorithm significantly decreases, accompanied by detail loss and distortion. In addition, most existing algorithms require a large amount of foggy datasets during model training, and model training takes a long time, which reduces the practicality of the model. In response to the above issues, this paper proposes an image dehazing model based on a small sample multi attention mechanism and multi frequency branch fusion (MFBF-Net). This model can effectively extract high-frequency and low-frequency detail information in the image, and reconstruct the real image to the greatest extent possible. The experimental results show that the dehazing model proposed in this paper exhibits good dehazing performance on small sample datasets, and has good performance in different concentrations of foggy scenes.
