Paper Abstract

Potato is a major crop all over the world. New farming trends involve modern agrotechnical techniques which significantly minimize the use of chemicals. The problem of selection of the measure and its environment emerged in the validated method used for assessment of the degree of coverage based on image analysis. The aim of this study was to indicate an adequate representative (staining) liquid, background and lighting. In search of a representative liquid enabling distinction between a sprayed and non-sprayed surface the problem of diversity in the brightness of contrasting surfaces was taken into consideration. Having conducted preliminary analyses, the diversity of the spectral composition of reflected light was used. The study resulted in finding an adequate representative working (staining) liquid in the form of diluted ink. The study also confirmed that white emulsion paint was the best background and that white halogen light was optimal for object illumination.
