Method and apparatus for SAR image recognition based on multi-scale features and broad learning

摘要

Disclosed are method and apparatus for SAR image recognition based on multi-scale features and broad learning. A region of interest of an original SAR image is extracted by centroid localization, the image is rotated and added with noise for enhancing the data volume, the image is downsampled, LBP features and PPQ features are extracted, an LBP feature vector X_LBP and an LPQ feature vector X_LPQ are cascaded to achieve dimension reduction by principal component analysis to obtain a fusion feature data X_m, the fusion feature data X_m is input to a broad learning network for image recognition and a recognition result is output. By fusing the LBP features and the LPQ features, complementary information is fully utilized and redundant information is reduced. The broad learning network is used to improve the training speed and reduce the time cost. As a result, the recognition effect is more stable, robust and reliable.
