I’m new here. Trying to learn a little bit about the unmixed image
My system: Windows10
Version of the OTB: OTB-7.3.0-Win64
QGIS version: 3.16.3-Hannover
I need to process some 4 band imagery using OTB Hyperspectral Unmixing. I’ve got to come up with a grayscale abundance image, expressed as a percentage with values from 1-100. I just can’t seem to make sense of the unmixed output and how it relates to the input/endmembers.
I work in flight simulation. To configure a sensor image, I’ve got to have a 5-band tif.
Band 1 is used to express my primary material as a grayscale value 0-255.
Band 2 is used to express my secondary material as a grayscale value 0-255.
Band 3 is used to express my tertiary material as a grayscale value 0-255.
Band 4 is the abundance of the primary material expressed as a percentage 0-100.
Band 5 is the abundance of the secondary material expressed as a percentage 0-100.
Tertiary mixture is derived from 4 and 5.
Can someone help me or point me to another resource?*
