Recognition of Remote Sensing Target Based on Wavelet Transform and Support Vector Machine

In recent years, support vector machines (SVMs) have demonstrated excellent performance in a variety of pattern recognition. This paper applies SVM for recognition of remote sensing target, using translation-invariant features generated from the discrete frame transform and Hu's invariant moments. Compared to the traditional features extraction, the proposed method produces more accurate classification results on the Brodatz texture album. To alleviate the problem of selecting the right kernel parameter in the SVM, we use a fusion scheme based on multiple SVMs, each with a different setting of the kernel parameter.
