Application of few-shot learning in high resolution remote sensing image classification and recognition

Remote sensing image classification and recognition has been a hot topic in deep learning and image classification and recognition research in recent years. One of the key issues is that the sample data scale is small and prone to over-fitting. Therefore, many image classification models and methods cannot be fully applied to remote sensing image classification. It is a practicable idea to combine few-shot learning with remote sensing image processing to solve the problem of remote sensing image samples by data augmentation and optimizing the recognition model. According to the development of few-shot learning, the principles of typical learning methods and their applications in related fields are summarized for feature extraction and model classification methods. The status and problems of remote sensing image processing are analyzed, and the methods are compared based on the applicable scenarios, advantages and disadvantages. Through the analysis of the application of few-shot learning in high score remote sensing image classification and recognition, it is found that after the attention mechanism and transfer learning are introduced, few-shot learning can be used for remote sensing image classification with small sample data.
