The invention discloses a method and system for detecting changes in high-resolution remote sensing images. Among them, the method includes: obtaining the neighborhood feature of each pixel in the two-temporal image; inputting the neighborhood feature into the branch convolutional neural network model to obtain the category of the image, wherein the category is a changed class and an unchanged class; branch convolution The neural network model is obtained by unsupervised pre-training of the image. The branch convolutional neural network model includes an input layer, a branch network, a fully connected layer and a classification layer. The branch network is used to use the neighborhood feature as a label and the neighborhood feature Convolutional dimensionality reduction, the classification layer is used to classify images into different categories. The invention solves the technical problem of low detection accuracy of image changes in the prior art.
Description
Technical field [0001] The present invention relates to the field of high Change Detection, in particular, to a high of remote sensing image change detection methods and systems. Background technique [0002] Surface ecosystems and human activities are dynamically developing and evolving. Real-time access to accurate information for surface changes to better protect the ecological environment, management of natural resources, social development, research, and understand the relationship between human activities and interactions with the natural environment of great significance. [0003] At present, many domestic and foreign proposed change detection method can basically be divided into two categories: for change detection pixel change detection and object-oriented. Change detection pixels for images comprises a conventional algebraic method, an image conversion method and the like. Image algebraic method is more representative of the change vector analysis method, which calculat...
