Abstract

The invention discloses a remote sensing scene image classification method based on multi-level dense feature fusion, and relates to a remote sensing scene image classification method. The objective of the invention is to solve the problem of low classification accuracy of hyperspectral images caused by high-dimensional characteristics of the hyperspectral images and small training samples in existing hyperspectral image extraction processes. The method comprises the following steps of: step 1, acquiring a hyperspectral image data set X and a corresponding label vector data set Y; step 2, establishing a lightweight convolutional neural network BMDF-LCNN based on dual-branch multi-level dense feature fusion; step 3, acquiring an optimal network BMDF-LCNN; and step 4, inputting a to-be-measured hyperspectral image into the optimal network BMDF-LCNN to perform classification result prediction. The method is applied to the field of image classification.

Description

technical field [0001] The invention relates to a remote sensing scene image classification method. Background technique [0002] At present, remote sensing images with high resolution are applied to many fields. Such as remote sensing scene classification [1] , hyperspectral image classification [2] , change detection [3-4] , geographic imagery, and land use classification [6-7] Wait. However, the complex spatial patterns and geometric structures of remote sensing images bring great difficulties to image classification. Therefore, it is particularly important to effectively understand the semantic content of remote sensing images. The purpose of this research is to find a simple and efficient lightweight network model that can accurately understand the semantic content of remote sensing images and correctly determine which scene category it belongs to. [0003] In order to effectively extract image features, researchers have proposed many methods. Initially, feature...
