Abstract: In the study of cloud type recognition of ground-based meteorological cloud images, the feature selection technology based on Local Binary Pattern (LBP) descriptors is the most common method due to its simplicity and effectiveness. However, the high-dimensional property of LBP features makes the performance and computational overhead of cloud type recognition unsatisfactory. To the end, an LBP feature selection algorithm based on F-statistics constructed by mutual information is proposed, which can achieve effective dimensionality reduction of high-dimensional LBP features, while ensuring the accuracy of cloud type recognition, greatly reducing the computational cost of feature selection process.
