Research of the spectral characteristics of healthy and fusarium-infected wheat seeds variety Moskovskaya 56 by hyperspectral spectroscopy

Abstract: In this paper, a spectroscopic identification method is considered for determining the maxima and minima of spectral lines to identify pathogenic microflora in grain seeds. The paper presents the justification for the application of the method of hyperspectral imaging, in order to identify the disease fusarium in the seeds of soft winter wheat. Based on the graphs, it can see the general picture of the influence of the disease fusarium on wheat grains. There is a general decrease in the reflectivity of the gra… Show more

“…The estimated accuracy parameters of the models demonstrate the greater predictive accuracy for the PCA-SVM approach, adapted to solving nonlinear tasks, compared to PCA-LDA (see Table 3 ). Qualitatively similar results for predictive ability were noted in the work [ 31 ].…”

“…Such analysis made it possible to reduce data dimensions as soon as the highly impact spectral regions were identified. The analysis was performed within two stages [ 31 ]. At the first stage, a linear transition to the new orthogonal variables the so-called principal components (PCs) was carried out, and the scores were obtained for corresponding spectra.…”
