Research Projects

Classification of Polarimetric SAR Data In this project we study general purpose algorithms for classification of PolSAR data, but specific application areas such as land use classification and sea ice classification are also considered. Our main focus is on unsupervised methods. We apply modern algorithms from pattern recognition and machine learning, such as spectral clustering, kernel methods, and information-theoretic learning, in an attempt to improve traditional algorithms such as the Wishart classifier. We also extend the features used in classification from statistics derived from single pixel densities to include statistical information of neighbouring pixels, texture, and information derived from physical modeling and decomposition theory.
