A Deep Vector Quantization Clustering Method for Polarimetric SAR Images

چکیده

Convolutional Neural Network (CNN) models are widely used in supervised Polarimetric Synthetic Aperture Radar (PolSAR) image classification. They powerful tools to capture the non-linear dependency between adjacent pixels and outperform traditional methods on various benchmarks. On contrary, research works investigating unsupervised PolSAR classification quite rare, because most CNN need be trained with labeled data. In this paper, we propose a completely model by fusing Autoencoder (CAE) Vector Quantization (VQ). An auxiliary Gaussian smoothing loss is adopted for better semantic consistency output map. Qualitative quantitative experiments carried out satellite airborne full polarization data (RadarSat2/E-SAR, AIRSAR). The proposed achieves 91.87%, 83.58% 96.93% overall accuracy (OA) three datasets, which much higher than H/alpha-Wishart method, it exhibits visual quality as well.

CFAR edge detector for polarimetric SAR images

Finding the edges between different regions in an image is one of the fundamental steps of image analysis, and several edge detectors suitable for the special statistics of synthetic aperture radar (SAR) intensity images have previously been developed. In this paper, a new edge detector for polarimetric SAR images is presented using a newly developed test statistic in the complex Wishart distri...
