N2 - The support vector machine (SVM) classification algorithm has received increasing attention in recent years in remote sensing for land cover classification. However, it is well known that the performance of the SVM is sensitive to the choice of parameter settings. The traditional single optimized parameter SVM (SOP-SVM) attempts to identify globally optimized parameters for multi-class land cover classification. In this paper, a novel multi-parameter SVM (MP-SVM) algorithm is proposed for image classification. It divides the training set into several subsets, which are subsequently combined. Based on these combinations sub-classifiers are constructed using their own optimum parameters, providing votes for each pixel with which to construct the final output. The SOP-SVM and MP-SVM were tested on three pilot study sites with very high, high and low levels of landscape complexity within the Sanjiang Plain: a typical inland wetland and fresh water ecosystem in northeast China.
