Abstract
An image processing system, comprising a scanning device having at least first and second light sources for illuminating an object to be scanned, the second light source configured to emit light at a different frequency spectrum than the first light source, a scanned image of the object generated using light emitted by the first and second light sources, the system further comprising a processor, wherein image data representing at least two images of the object respectively generated using light from the first and second light sources is processed by the processor in order to decompose the images into component data representing respective higher and lower spatial frequency components, and wherein component data relating to at least the lower spatial frequency components for the first and second images is transformed in order to generate transformed data for the low spatial frequency components, and method.
