Abstract

The invention discloses a polarized SAR image classification method based on a K mean value and a depth SVM. The polarized SAR image classification method mainly solves the problems of low classification accuracy and classification efficiency of an existing polarized synthetic aperture radar (SAR) classification method. The polarized SAR image classification method comprises the steps of (1) inputting images; (2) performing filtering; (3) extracting features; (4) establishing a misclassification set; (5) establishing a nearest neighbor sample set; (6) establishing a final training set; (7) establishing a depth support vector machine classifier; (8) performing classification; (9) calculating accuracy. By means of the polarized SAR image classification method, polarized SAR images can be classified accurately, the classification time of the polarized SAR images can be shortened effectively, and target recognition and tracking of the polarized SAR images are achieved.
