投影方向

• For the feature extraction and classification of hyperspectral remote sensing image data , especially for the easy mixed classification problem , a projection index is established ; by optimizing the projection index , a projection direction is calculated to classify the easy mixed classified pixels
  针对高光谱遥感图像数据的特征提取和分类问题，尤其是针对某些易混分地物的分类问题，研究和建立相应的投影寻踪指标，通过优化这种投影指标，寻找能够更容易区分易混分地物的投影方向。
