Abstract: To further improve the recognition accuracy of remote sensing image building area recognition, a classification method based on median robust extended local binary pattern(MRELBP) feature, Franklin moment and optimized support vector machine(SVM) by cuckoo search is proposed. Firstly, calculate the texture feature vector of the image block with MRELBP feature operator and use Franklin moment obtain the shape feature vector, the texture feature vector and the shape feature vector are combined into a comprehensive feature vector. Then train the SVM with training image samples, meanwhile, use cuckoo search to optimize the kernel function parameter as well as the penalty factor. Lastly, input the recognizing image into the SVM to get the result of building area recognition. The results of 30 groups of experiments show that, compared with the classification method based on RGB and SVM, the classification method based on LBP and SVM and the classification method based on Zernike moment and SVM, the accuracy of the remote sensing image building area identified by the proposed method is higher.
