Paper Abstract

Narrowband image extraction is an essential preprocessing for multispectral imaging of filter array. This paper proposes an automatic method to extract narrowband images from a multispectral image. During offline phase, the method first employs horizontal and vertical projections to obtain initial positions of subsampling points. Then, integerpixel searching and half-pixel searching optimizes subsampling location. During on-line phase, 1:4 or 1:16 interpolation generates interpolation grids. Finally, four narrowband images are obtained according to the optimized subsampling points and interpolation grids. The experimental result indicates that this method effectively extracts narrowband images from originally mosaic images of multiple spectrums.
