Abstract:Spectral response curve of hyperspectral image contains rich spectral characteristics. Fractal dimension can represent feature of complex spectral curve. A step measurement fractal dimension calculation algorithm of hyperspectral curve is proposed. A fractal feature image generation procedure of hyperspectral data is designed. Experiments for fractal dimension values of different objects' spectral curves show fractal can be used to represent the spectral feature. Finally, the applicability of spectral curve fractal dimension to hyperspectral data processing is discussed.
Keywords:hyperspectral images  spectral response curve  fractal feature
