| 摘 要： | 分析了在光谱图像压缩的性能评价中常用的几种光谱失真客观度量方法,针对光谱曲线的关键区域,改进了相对光谱二次误差,提出了一种基于光谱导数曲线的光谱失真客观度量方法.该方法与光谱图像的应用需求一致,对谱线特征吸收峰的变化尤为敏感.仿真实验结果表明,该方法能有效地度量光谱图像压缩引入的各种光谱失真. |
| 关 键 词： | 压缩 光谱图像 性能评价 光谱失真 相对光谱二次误差 |

| Abstract: | Several objective measurements of spectral distortion widely used in quality evaluation of spectral image compression were analyzed.Considering characteristics of spectral distortions,RQE was modified and a new distortion measurement method based on spectrum differential was brought forward.This method agrees with spectral image application,and it is extremely sensitive to the change of spectrum absorbing feature point.The experiment result proves that this method can measure spectral distortions effectively. |
| Keywords: | Compression Spectral image Quality evaluation Spectral distortion Relative Spectral Quadratic Error (RQE) |
