查询词典 classification system

According to the dichotomy pixel Spatial Modeler modeling tool used to calculate the vegetation coverage in mining, use of non-supervised classification of vegetation coverage on the mining area classification, coloring, and finally come to mine the vegetation coverage in 1990-2000 category map, quantitative description of the Shanxi Province, 10 years of vegetation cover change: The region coverage to low, medium and high-based, the proportion remained almost unchanged, a significant increase in very low coverage, high coverage significantly decline.

根据像元二分法利用的建模工具Spatial Modeler计算出矿区的植被覆盖度，利用非监督分类方法对矿区的植被覆盖度进行分类、赋色，最后得出矿1990-2000年的植被覆盖度分类图，定量的说明了山西省10年间的植被覆盖变化情况：全区覆盖度以低、中和中高为主，所占比例几乎保持不变，极低覆盖度有明显增加，高覆盖度有明显下降。

People have proposed lots of feature extraction and classification algorithms and achieved great successful in the last few years, but there are also many disadvantages that restrict the applications to some extent.

Landscape pattern analysis based on landscape metrics is a basic content of the research on landscape ecology. More and more researches proved that not only scale effects and the precision of remote sensed data had significant influence on landscape metrics, but also the difference of land use classification would make the change of landscape metrics. However, we still have not found out how land use classification affects landscape metrics and associated influence mechanism.

基于景观格局指数的空间格局分析是当前景观生态学研究的重要基础内容，不仅数据源准确度、尺度效应显著影响景观格局指数，土地利用类型划分也对景观格局指数具有显著影响，但我们对这种影响的总体理解尚很缺乏。

The conventional classification methods are hard classification based on the spectral statistic features of the pixels.

这些土地利用类型的波谱特征为进行土地利用分类提供了波谱理论基础。
