valevärvipilt
false color composite
  • RGB-värvimudelil põhinev rasterpilt, mille värvikanaleid kasutatakse valitud spektrivahemike erinevates kombinatsioonides: nt R võib olla hoopis infrapunakiirguse teatud spektriala

valevärvipilt
Usage examples
  • Valevärvipildil on punase värviga kujutatud lähisinfrapunase lähisinfrapunase spektripiirkonna pilti. [...] Valevärvipilte kasutatakse taimkattega ja taimkatteta pindade heleduserinevuste visuaalseks võimendamiseks.
värvikomposiit
Usage examples
  • Andmetöötlus ESTHub-il: värvikomposiitide automaatne loomine Sentinel-1, Sentinel-2 ja Sentinel-3 andmetest
false color composite
Usage examples
  • This type of composite image is termed a false color composite, since what we are seeing in blue, green and red light is information that is not from the blue, green and red visible bands, respectively.
color composite
Usage examples
  • Each band of a multispectral image can be displayed one band at a time as a grey scale image, or in a combination of three bands at a time as a color composite image.

valevärvipilt
false color image
  • tehislikult genereeritud värvipilt, millel sinine, roheline ja punane pannakse vastavusse teistsuguste lainepikkustega, kui nad on loomulikult nähtavad inimese silmale
  • artificially generated colour image in which blue, green and red colours are assigned to the wavelength regions to which they do not belong in nature
Good to know
  • A false color image is used to reveal or enhance features otherwise invisible or poorly visible to a human eye. In other words, a false color composite is a multispectral image interpretation using the standard visual RGB band range (red, green, and blue).
valevärvipilt
Usage examples
  • Valevärvi pildi tegemiseks kasutasin IDRISI moodulit COMPOSITE, milleks on mul vajalikud kolme spektripiirkonna pildid: rohelise, punase ja lähisinfrapunase piirkonna pildid.
valevärvikomposiit
Usage examples
  • Joonisel 3a on näidatud valevärvides komposiit SWI (Shortwave Infrared) ja joonisel 3b protsessori pilvemask.
false color image
Usage examples
  • NearIR is usually assigned to red on the image; thus, vegetation often appears bright red in false color images , rather than green, because healthy vegetation reflects a lot of nearIR radiation.
false color composite
Usage examples
  • The most striking characteristic of false colour composites is that vegetation appears in a red-purple colour.
