Abstract

The invention provides an image recognition method and device, a storage medium and electronic equipment. The image recognition method comprises the steps of obtaining a first image and a second imageof a target area; wherein the acquisition conditions of the first image and the second image are different; determining a difference image based on the heterogeneity information of the first image and the second image; carrying out FCM calculation and secondary classification on the difference image to obtain an initial label field image; and identifying changes in the second image relative to the first image based on the difference image and the initial label field image. The edge continuity and the region integrity of the obtained difference image are good, the probability that when an ICMRF algorithm is used for calculating the difference image, iteration frequency is increased, and the difference image is prone to falling into the local optimal solution is reduced, the change of the second image compared with the first image can be accurately recognized, and then the accuracy of the change region is improved.

Description

technical field

[0001] The present disclosure relates to the technical field of radar image processing, and in particular, to an image recognition method, a corresponding device, a storage medium, and an electronic device. Background technique

[0002] Synthetic Aperture Radar (SAR) has the advantages of all-day, all-weather, and large-scale observation, and can also obtain high-spatial-temporal resolution and high-precision SAR images. It has broad application prospects in the field of disaster change detection. Among them, SAR image change detection refers to the analysis and comparison of multiple SAR images obtained in the same area at different times and under different imaging conditions, and then determine the changed area. Point change information is more helpful to the understanding and prediction of disasters; therefore, change detection in SAR images has been specifically applied in urban monitoring, land use, and disaster early warning.
