This article describes a method for the subpixel classification of Terra ASTER satellite image for vegetation mapping of the tundra–taiga ecotone in the Tuliok River, Khibiny Mountains, Russia. It was demonstrated that this method allows to determine the position of the boundaries of ecotone ...
The launch of an identical Sentinel-2B satellite will further reduce revisit time to 5 days globally. Both Sentinel-2A/B satellites will use a Global Reference Image (GRI) derived from orthorectified Sentinel-2 cloud-free images to improve geolo- cation accuracy and repeatability to meet the ...

In this paper, a new method is presented for a subpixelic land cover classification using both high-resolution structural information and coarse-resolution (CR) temporal information. To that aim, the linear mixture model is used for pixel disaggregation. It enables us to describe a CR time seri...
Satellite Based Estimation of Urban Surface Emissivity with the Use of Sub-Pixel Classification Techniques The basic premise of this method is a sub-pixel classification of urban surface into vegetation, impervious and soil, based on spectral mixture analysis. The proposed approach was applied to Land...

6) subpixel and low probability 亚象元、低概率补充资料:风险估测 风险估测 【风险估测】运用概率及数理统计方法估测某一风险发生的概率及其损失后果的频率、性质和概率,以准确地估计损失的严重后果。或者说,风险估测就是运用概率统计方法对风险事件发生和风险事件的后果加以估测,从而给出一个较准确的概衣水平...
Use of this criterion outperformed two other commonly used stopping criteria: a predefined number of training iterations and a cross-validation approach. 展开 关键词: Early stopping criterion neural network subpixel classification DOI: 10.1109/LGRS.2010.2052782 被引量: 28 ...
This paper focuses on the effect of imposing these constraints onto the MultiLayer Perceptron (MLP) for a multi-class sub-pixel land cover classification of a time series of low resolution MODIS-images covering the northern part of Belgium. Two constraining modes were compared, (i) an in-...
