Abstract

The invention discloses a multi-spectral remote sensing image-based ship target quick-detection method, and belongs to the technical field of remote sensing image-based target detection. According to the method, the information of the spectral domain and the spatial domain is fully utilized, and the Walsh-Hadamard transform domain coefficient of a multi-spectral remote sensing image is processed to extract the saliency characteristic of the spatial domain. The method is used for sea ship target detection. The method of the invention can effectively overcome the defects of the traditional multi-spectral image ship detection method such as high computational complexity and complex parameter setting. A large number of real multi-spectral remote sensing data experiment results show that the method can achieve an effect of quick and accurate sea ship target detection, and is of high robustness to spectral noise and cluttered marine background. The method is of great application value in aspects like marine fisheries management, marine transportation control and military maritime monitoring.

Description

technical field [0001] The invention belongs to the technical field of remote sensing image target detection, and in particular relates to a method for rapidly detecting ship targets in multi-spectral remote sensing images. Background technique [0002] The multi-spectral imaging sensor can obtain the spectral information of the substances corresponding to each spectral segment in the spectral dimension, and at the same time obtain the spatial information of the scene in the spatial dimension, forming a multi-dimensional data body containing rich geographical environment information. Since there are large differences in the spectral characteristics of each spectral band between artificially constructed targets and natural material backgrounds, multispectral image data has unique advantages in ground object detection and can be used for automatic target detection tasks. Especially in marine transportation, marine fishery management, and military monitoring, the detection of s...
