摘要
光谱曲线形状与目标性质是对应的,通常以吸收峰位置作为高光谱图像中目标的波谱特征并进行比较。为解决高光谱图像中目标组成均质性差所带来的光谱特性表征和描述困难,基于单一地物的波谱响应特征具有内在一致性这一特点,提出了吸收峰位置融合提取模型。应用事例说明,该方法对高光谱图像中目标波谱特性的统一描述具有较高的实用价值。
Spectral curve shape is corresponding to the target character, usually uses the absorption peak position as hyperspectral image of target spectral characteristics and comparison. In order to solve the problem of characterization and description on spectral characterization result from target composition heterogeneity difference, Based on a single target ＇s feature spectral response characteristic has its intrinsic uniformity, absorption peak center wavelength fusion extraction model is proposed. The application results show that it has a high practical value on uniform description of hyperspectral image target spectrum characteristics.
