ROUGH LUMBER IDENTIFICATION ALGORITHM
The article deals with the accounting procedure of rough lumber. It introduces an algorithm of digital image processing enabling rough lumber identification. The analysis of publications on the discussed subject has shown a number of disadvantages of the current accounting procedures: they are rather expensive and their applicability is limited in certain cases. The proposed algorithm combines a number of methods; the most important are binarization, Sobel operator, transformation to a Cartesian coordinate system, Fourier theory, Euclidean distance calculation. The latter is used to compare a digital image identity.
