Grey level co-occurrence matrix (GLCM) for textile print analysis

Print mottle is a print defect. This defect has great attention in quality assessment. determined by the grey level co-occurrence matrix (GLCM). An important parameter GLCM processing direction angle of pixels digitalized image. research aimed to investigate influence angle, which an input processing, on output parameters, such as entropy, energy, contrast, correlation, and homogeneity. Hence, prints were generated four different colors (cyan, magenta, yellow black) white polyester elastase fabric sublimation printing. The non-uniformity for each color was processed at angles, 0° (horizontal), 90° (vertical), 45° (right-diagonal), 135° (left-diagonal). Values parameters obtained angles slightly regardless color. choice influenced values parameters. average all directional taken. method can be used colors, patterns, levels evaluate their uniformity.
