    Research output: Patent


    A method of processing a multispectral or hyperspectral image captured in respect of an area of interest including a variably reflective surface, said image comprising at least one visible-wavelength signal and a NIR signal, the method comprising: -performing an image matching process using an iterative robust estimation method in respect of data points derived from said at least one visible-wavelength signal so as to estimate a scaling coefficient representative of specular reflection from said surface; -applying said scaling coefficient to said NIR signal such that a specular reflection component of the resultant scaled NIR signal is substantially the same as that of said at least one visible-wavelength signal; and -subtracting said scaled NIR signal from said at least one visible- wavelength signal to generate a visible-wavelength output image signal.
