摘要:
The number and categories of the existing cloud image segmentation datasets are limited, and the segmentation model is not strong targeted enough and occupies large memory, resulting in which has a not high precision and efficiency. Considering these problems, a dataset GBCD-GT with large amount of data and multiple cloud images is constructed in this paper. On this basis, a ground-based cloud image segmentation model BFSegNet based on bilateral feature fusion is proposed. The model extracts detail features and semantic features respectively through detail branch and semantic branch, and then fuses the two features together through feature fusion module, finally realizes cloud image segmentation through up-sampling. After multiple groups of comparative experiments, it is shown that the model BFSegNet can achieve accurate cloud image segmentation under the premise of a lower number of parameters, making the pixel accuracy up to 94.39% and the mean intersection over union up to 73.26%. Moreover, the prediction time of single image of the model is only 1.216s, which improves the segmentation efficiency of the model. It lays a foundation for the practical application of the model. © 2022 IEEE.
