document: Generalized mosaicing : wide field of view multispectral imaging We present an approach to significantly enhance the spectral resolution of imaging systems by generalizing image mosaicing . A filter transmitting spatially varying spectral bands is rigidly attached to a camera . As the system moves , it senses each scene point multiple times , each time in a different spectral band . This is an additional dimension of the generalized mosaic paradigm , which has demonstrated yielding high radiometric dynamic range images in a wide field of view , using a spatially varying density filter . The resulting mosaic represents the spectrum at each scene point . The image acquisition is as easy as in traditional image mosaics . We derive an efficient scene sampling rate , and use a registration method that accommodates the spatially varying properties of the filter . Using the data acquired by this method , we demonstrate scene rendering under different simulated illumination spectra . We are also able to infer information about the scene illumination . The approach was tested using a standard 8-bit black/white video camera and a fixed spatially varying spectral -LRB- interference -RRB- filter
