[S3] Spectral-Spatial Classification of Hyperspectral Images Based on Hidden Markov Random Fields, IEEE TGRS.

P. Ghamisi, J. A. Benediktsson, M. O. Ulfarsson, Spectral-Spatial Classification of Hyperspectral Images Based on Hidden Markov Random Fields, IEEE TGRS. 52(5): 2565-2574, 2014. [Code]

Description:

In this work, a new fully automatic framework for the classification of hyperspectral images was implemented. The new method is based on combining Hidden Markov Random Field (HMRF) segmentation with Support Vector Machine (SVM) classifier. In order to preserve edges in the final classification map, a gradient step is taken into account. Experiments confirm that the new spectral and spatial classification approach is able to improve results significantly in terms of classification accuracies compared to the standard SVM method and also outperforms other studied methods. The HMRF was implemented by Dr. Quan Wang and the spectral-spatial classification approach was implemented by me. In order to use the software, please refer to the following articles:
