The invention belongs to the field of image identification, and particularly relates to a classification and identification method for a foggy water surface image and a clear water surface image. The method comprises the steps of acquiring water surface images to be identified; establishing a water surface image database; extracting features of the water surface images; training and learning classification and identification features of the fog of the water surface images; and identifying the foggy water surface image to be identified and the clear water surface image to be identified. The method can greatly improve the intelligence of a visual system of a water surface aircraft. The features can be extracted simply, few features for identification are available, and the identification rate is high; and being used for earlier stage processing of the visual system of water surface ship or an unmanned surface vehicle, the method can adaptively judge water surface weather environment, and ...

The invention relates to a small sample remote sensing image classification method based on a restrictive prototype comparison network. The method comprises the following steps: 1, performing preprocessing such as segmentation and data enhancement on original hyperspectral remote sensing data; 2, randomly selecting samples in a source domain and a target domain to form a comparison support set and a query set; 3, designing and constructing a deep feature extraction network, and updating network parameters by utilizing a distance between a category prototype of a comparison support set and a query set sample; 4, applying triple restrictions to the category prototype to obtain a more accurate prototype for network training; and 5, finely adjusting the network model and predicting category labels of all unmarked samples. The hyperspectral remote sensing image classification method can realize accurate classification of hyperspectral remote sensing images under the condition of a small number ...
