| 摘 要： | 由于高光谱图像具有很高的光谱分辨率，能够提供更为丰富的地面信息，正在受到国内外的广泛关注。针对高光谱分析过程中产生的Hughes现象，分析了其产生的原因，指出可以在图像预处理阶段对样本进行低通滤波，有效地削弱这种影响。

| Abstract: | Hyperspectral images , which can provide more detailed ground truth information due to the higher spectral resolution, have gathered more and more people's attention. The paper introduces the Hughes phenomenon which can severely deteriorate classification performance, then the author proved that by utilizing a lowpass filter more accurate classification results can be achieved because of the better class separability. |
