ETM＋遥感影像最佳波段融合质量评价
Fusion of ETM+ Image Optimal Bands Composite and Its Quality Evaluation
摘要
Abstract
The optimum index factor( OIF) method was taken to determine the optimal bands combination, and the results indicated that bands 5,4,2 in the ETM+ remote sensing data was the optimal combination. Then, four fusion algorithms were taken based on the optimal bands combination and the panchromatic band of ETM+ remote sensing da-ta by four fusion algorithms including multiplicative transformation, brovey transformation, HIS transformation, wavelet transformation. The results of different fusion methods were evaluated qualitatively and quantitatively by comparison with the correlation between the original image and the fused images. The results indicated that wavelet transformation was the best method to improve the spatial resolution. The brovey transformation took the second place. The brovey transformation was the best method to maintain the spectral quality, and the wavelet transformation took the second place. So, the brovey transformation and wavelet transformation were selected.关键词
