Some consideration is given to the choice of the most appropriate colour coding in the principal component composite images.The presentation of multichannel image information in terms of a false-colour composite can, in general, be achieved with less sacrifice of data if the three leading principal component images are used rather than the three conventional raw channelsRegister to receive personalised research and resources by email/doi/pdf/10.1080/01431168508948510?needAccess=trueMedicine, Dentistry, Nursing & Allied HealthThe generation and interpretation of false-colour composite principal component imagesWe use cookies to improve your website experience. 0000001745 00000 n
