Because these different forms of electromagnetic radiation - on this "simplistic" level - are fundamentally so similar, they are today commonly viewed as composing a single spectrum.

因为这些各异的电磁辐射在“简单”层面上，即本质上是如此相似，所以如今把它们视为一个光谱中的组成部分。

The algorithm integrates the advantages of infrared image and visible image and makes the recognition result by multiple-spectral information better than single spectrum information.

该算法充分利用红外与可见光图像的成像特性，对两个谱段图像的目标识别结果进行决策级的融合，使多谱识别效果大大优于单谱识别。
