Subject of study. This study focuses on the acquisition, processing, and interpretation methods and algorithms for spectral images aimed at evaluating surface defects in fruits. Aim of study. The aim of this study is to develop a method for assessing fruit preservation techniques based on the automatic detection and quantitative evaluation of surface defects using imaging spectroscopy. Method. Spectral images were acquired using an acousto-optical imaging spectrometer with a spectral range of 450–850 nm and a bandwidth of 2.5 nm at a wavelength of 650 nm, with a 5 nm step. For processing the spectral images, well-established operations and algorithms for data enhancement and analysis were employed. These included correction for uneven illumination, correction for spatial and spectral inhomogeneity of the optical system’s transmittance coefficient, various image filtering techniques, and threshold binarization... |
