| 摘 要： | 以整个中国区域为例,采用3种检测方法对Spot vegetation S10影像上存在的云和雪盖的检测结果进行了对比分析.结果表明,BISE检测器得到的云层和实际最为接近,用Spot vegetation状态地图得到的云层过少,而用Spot vegetation检测器V2.0得到的云和雪盖像素有部分重叠.最后利用云、雪盖像素在时间序列上的相邻像素进行平滑处理方法达到去云和雪盖的目的,研究结果对于Spot vegetation S10影像的噪音消除和应用精度的提高具有借鉴意义. |

| Abstract: | Taking China as the test area,the three kinds of methods for detecting the cloud and snow on Spot Vegetation S10 images are compared. According to the comparison,BISE is the best for detecting cloud among the three; the cloud extracted by the status map (SM) is too little; cloud and the ice and snow extracted by the detector V2.0 overlap each other. The averaging of timely neighboring (before and after the cloud pixels) cloudy (or ice and snow)-free pixels is adopted to remove cloud,ice,and snow. The result is valuable for noise reduction and application accuracy improvement of Spot Vegetation S10. |
