Abstract EN
The combination of spectral and spatial information is known as a suitable way to improve the accuracy of hyperspectral image classification.
In this paper, we propose a spectral-spatial hyperspectral image classification approach composed of the following stages.
Initially, the support vector machine (SVM) is applied to obtain the initial classification map.
Then, we present a new index called the homogeneity order and, using that with K-nearest neighbors, we select some pixels in feature space.
The extracted pixels are considered as markers for Minimum Spanning Forest (MSF) construction.
The class assignment to the markers is done using the initial classification map results.
In the final stage, MSF is applied to these markers, and a spectral-spatial classification map is obtained.
Experiments performed on several real hyperspectral images demonstrate that the classification accuracies obtained by the proposed scheme are improved when compared to MSF-based spectral-spatial classification approaches.
