Document Type and Number:
Japanese Patent JP6958743
Kind Code:
B2
Abstract:
An image processing device 500 for detecting and correcting areas affected by a cloud in an input image is provided. The image processing device 500 includes: endmember extraction unit 501 that extracts a set of spectra of one or more endmembers from the input image; cloud spectrum acquisition unit 502 that acquires one cloud spectrum in the input image; endmember selection unit 503 that compares the endmember spectra with the cloud spectrum, removes one or more spectra from the set of spectra of the endmember spectra, the one or more spectra being same as or similar to the one cloud spectrum, and outputs a resultant set of spectra as an authentic set of spectra; and an unmixing unit 504 that derives, for each pixel in the input image, one or more fractional abundances of the one or more endmembers and a fractional abundance of cloud in the authentic set of spectra, and detects one or more cloud pixels in the input image.
