METHOD FOR DETERMINATION OF DEGREE OF LEAF DISEASE AFFECTION ON CEREALS

摘要

A method for determination of degree of leaf diseases affection of cereals includes formation of leaf image by means of a scanner, spectral analysis of the image using software and assessment of the determined data by the method of computer diagnostics. Assessment is carried out by analyzing of function of frequency distribution of red component intensity on the leaf image with expansion of the function in two Gaussian components which characterize affected and nonaffected fraction of the leaf.
