The result showed that it was speedy to extract spectralfeature of cucumber disease by the gray of images.
实验结果表明,用亮度信息提取霜霉病害的多光谱图像特征波段,能快速提取病害的特征波段信息。

Great achievements in some aspects such as pure pixel extraction, spectral unmixing, matched filtering and spectralfeature fitting have been made.
在纯净像元提取、混合像元分解、匹配滤波、光谱特征拟合等方面进行了探索。
