This paper presents the main characteristics and functionalities of a system based on image processing techniques applied to quality assessment of yarns. In Textile Industry we used image processing to determine yarn mass parameters as well as yarn production characteristics. A low cost solution based on a web-pc camera plus the optics of a low cost(More)
This paper presents the design and implementation of a remote experiment for controlling the level of a two-tank system. It describes also the management of the team work: it was performed in a remote collaborative methodology by two students of the fourth year of the Industrial Electronics Master Course at University of Minho (UM) and one student from the(More)
—We demonstrate that one can adequately characterize yarn hairiness by imaging the yarn along a single projection direction using coherent optical processing. A system that simultaneously characterizes the yarn hairiness along two orthogonal projection directions was constructed. Provided that a sufficiently high number of yarn segments are sampled, a(More)
