Abstract
The article deals with the issues of computer simulation of algorithms for processing spectral images, namely: the procedure for increasing their clarity. For this purpose, a spectral image obtained from a hyperspectrometer is used, as well as additional information from a high-resolution color video camera. The hyperspectrometer and the color video camera form a hyperspectral system in which various processing procedures can be implemented. The article considers a relatively simple processing algorithm with use of E. Land's retinex theory. A block diagram of the image processing stages is presented, as well as the results of computer modeling using real spectral images. Comparative quantitative characteristics of reference and processed images are analyzed. It is shown by modeling that with insignificant spatial distortions, the number of singular points (gradients) of the image, and, consequently, the clarity of the original spectral image increase by several times.
