WebApr 10, 2024 · Spectral unmixing (SU) of hyperspectral images (HSIs) is one of the important areas in remote sensing (RS) that needs to be carefully addressed in different RS applications. Despite the high spectral resolution of the hyperspectral data, the relatively low spatial resolution of the sensors may lead to mixture of different pure materials within the … WebRule 1: The control must be at least as bright as the experimental sample. This is the same as the first rule of compensation, so no differences here. Rule 2: There must be good separation between the positive and negative. While this is not explicitly stated in the rules of compensation, is it good practice.
