Original Paper


The paper presents methods and tools for assessment of main quality features of grain samples based on color image and spectra analyses. Visible features like color, shape, and dimensions of the grain sample elements are extracted from the images. Information about its color and surface texture is obtained from the grain spectral characteristics. The categorization of the grain sample elements in three quality groups is accomplished using two data fusion approaches. The first approach fuses the results from color and shape characteristics obtained using image analysis only. The second approach fuses the shape data obtained by image analysis and the color and surface texture data obtained by spectra analysis. The three data fusion methods give the following errors in the categorization of the grain sample elements: 15.3, 8.6, 5.3 %.
