A method of removing streaks from multi-band digital images is presented in which
a multi-band image is transformed to an advantageous spectral space, in which a
streak removal operation is applied to the image in the advantageous spectral space.
The streak removal operation is a method of removing columnar streaks from a multi-band
digital image of the type in which it is assumed that pixels in a predetermined
spatial and spectral region near a given pixel are strongly related to each other
and employing gain and offset values to compute streak removal information, a test
is performed for a strong relation between the pixels in a predetermined region
spatially and spectrally near a given pixel and streak removal information is computed
only if such a strong relationship exists, whereby image content that does not
extend the full length of the image in the column direction will not be interpreted
as a streak.
