Example text

The main advantage of this approach is its simplicity. However, the closest fixed vicinity area does not always accurately reflect information about spatial structures, especially at the border of regions. Pesaresi and Benediktsson have proposed to use morphological filters as an alternative way of performing joint classification. The idea behind a morphological profile consists in progressively simplifying the image [6, 7]. This means, that we include the geometrical information in classification procedure.

The spatial resolution here is 20 m/pixel. It has 16 classes of interest. Results for Indiana dataset are shown in Figs. 4, 5, and 6. An SVM classification on the original hyperspectral image were performed in Figs. 1 and 4, then the classification map of SVM with different segmentation maps obtained by proposed techniques were appeared. Figures 2 and 4 were the obtained classification maps, with the global accuracies (Overall accuracy, Average accuracy and Kappa factor) and Figs. 3 and 5 presented the average accuracy of approaches for different classes.

1007/978-3-319-10849-0_5 42 M. Borhani and H. Ghassemian Therefore, the including of information about spatial structures into classifier should improve the classification. The question is how to define these structures automatically? This information is not directly accessible from camera recordings as the spectral information. The second question is how to combine spectral and spatial information? Perhaps the most intuitive way to consider the spatial information is to assume that for a given pixel; its closest samples belong with a high probability to the same class, and thus classify a central pixel taking into account its closest samples.
