I-S-15 (general) Use of image processing and image analysis in graphic and textile research

Digital image: acquisition, digitisation, pixel. Colour-, greyscale- and binary image, image formats, bitmap vs. vector graphics. Software for digital image processing and analysis. Histograms and point operations: changing brightness or contrast, global thresholding, histogram equalisation, arithmetic and logic operations. Linear and nonlinear filters: filter matrix (kernel), convolution, smoothing and sharpening, noise removal. Detection of edges and contours: partial derivatives and gradients of image function, operators. Morphological filters: structural element, basic morphological operations – dilation, erosion, opening, closing, outlining, skeletonisation. Regions in binary images: connected components labelling, descriptors of binary regions. Fundamentals of spectral techniques: 2D discrete Fourier transform (DFT).
Applications in the area of papermaking, printing and textile engineering: dirt count in pulp and paper, print quality determination using conventional or modern nonimpact printing technologies, study of substrate-printing ink interactions, FFT analysis of formation and regular structures in paper, fabric porosity and yarn diameter determination.
