Remote sensing image riverway target detection method and device based on feature fusion

Abstract

The invention relates to a remote sensing image riverway target detection method and device based on feature fusion, and a computer readable storage medium. The method comprises steps of a remote sensing image containing a riverway being collected and inputted; performing enhancement preprocessing on the remote sensing image by using a multi-scale contrast improvement method; shear wave transformation being carried out on the image after enhancement preprocessing to obtain variance maximum shear wave feature maps of different scales and directions; extracting an SUSAN edge feature map from theimage after enhancement preprocessing by using a similarity comparison method; calculating information entropies of the shear wave feature map and the SUSAN edge feature map, and obtaining a featurefusion map by using an information entropy weighting method; and performing threshold segmentation and morphological operation on the feature fusion image to obtain a final river target detection result image. According to the method, the capability of river channel detection under the remote sensing image is improved, and problems of low precision and high false alarm rate of traditional river channel detection are avoided.

Description

technical field [0001] The invention relates to the field of target detection in remote sensing and infrared image processing, in particular to a feature fusion-based remote sensing image river target detection method, device and computer-readable storage medium. Background technique [0002] The task of object detection in remote sensing images is to mark one or more objects of interest in a given aerial or satellite image. As an important geographical target, river channel is a research hotspot in the field of remote sensing detection, and has a wide range of applications in land monitoring, ship navigation, water and soil conservation, and flood disaster prevention. There are many types of geographical targets in remote sensing images, and the spatial detail information is rich, which interferes with the detection of river channels, making the detection more difficult. At present, in the existing remote sensing river target detection literature, the main methods of river...
