چکیده

In the last decades it often has been shown that Multilayer Perceptrons (MLPs) are powerful function approximators. They were successfully applied to a lot of different classification problems. However, originally they only deal with real valued numbers. Since PolSAR data is a complex valued signal this paper propose the usage of Complex Valued Neural Networks (CVNNs), which are an extension of MLPs to the complex domain. The paper provides a generalized derivation of the complex backpropagation algorithm, mentions regarding problems and possible solutions and evaluate the performance of CVNNs by a classification task of different landuses in PolSAR images.

Classification of Fully Polarimetric Sar Satellite Data Using Genetic Algorithm and Neural Networks

A novel method for supervised classification using fully polarimetric SAR data is proposed in this research. First a set of polarimetric parameters are extracted from SAR complex analysis and target decomposition theorems. Due to a large number of polarimetric parameters, the heuristic search method of Genetic Algorithm (GA) is used to select an optimum set of parameters as the feature vector. ...

Optimum Ensemble Classification for Fully Polarimetric SAR Data Using Global-Local Classification Approach

In this paper, a proposed ensemble classification for fully polarimetric synthetic aperture radar (PolSAR) data using a global-local classification approach is presented. In the first step, to perform the global classification, the training feature space is divided into a specified number of clusters. In the next step to carry out the local classification over each of these clusters, which cont...
