Texture Profiles and Composite Kernel Frame for Hyperspectral Image Classification

摘要

It is of great interest in spectral-spatial features classification for High spectral images (HSI) with high spatial resolution. This paper presents a new Spectral-spatial method for improving accuracy of hyperspectral image classification. Specifically, a new texture feature extraction algorithm based on traditional LBP method is proposed directly. Texture profiles is obtained by the proposed method. A composite kernel framework is employed to join spatial and spectral features. The classifiers adopted in this work is the multinomial logistic regression. In order to illustrate the good performance of the proposed framework, the two real hyperspectral image datasets are employed. Our experimental results with real hyperspectral images indicate that the proposed framework can enhance the classification accuracy than some traditional alternatives.
