COMPUTER SIMULATION OF A MULTIPLICATIVE METHOD FOR GENERATING DIGITAL SPECTRAL IMAGES
The article discusses the features of the formation of digital spectral images corresponding to narrow registration zones. The processes of signal transformations are analyzed with the multiplicative method of forming digital spectral images. Computer simulation results are discussed with the purpose of qualitative and quantitative comparison of images obtained in differential and multiplicative digital spectral imaging. The spectral characteristics corresponding to the initial multispectral images are presented. An example of images of test objects obtained by the differential and multiplicative method from the original digital spectral images is illustrated. The advantage of the multiplicative method in comparison with the differential method is shown for a quantitative comparison of the maximum and minimum values of brightness samples in the corresponding resulting spectral images.
