Recently many vectorizing methods have been developed and widely used to transform images into punctual data. However, conventional methods are used restrictively in vectorizing and needed for intervention by supervisors. To overcome the drawback, in this paper, we propose a vectorizing method based on image processing and linearization, and develop its application program. We show the effectiveness of the proposed method through experimental results on five test images.

Tension control of fiber manufacturing process system is usually achieved by using loadcell and powder clutch, which require additional mounting space, reduce the reliability in harsh environments and increase the cost of the system. The physical properties of textile fabrics are very sensitive to several factors(temperature, humidity, radius change of warp beam etc.)which result in tension change. In this paper, the optimal tension control of servo motor driver system using PI control algorithm is presented. The proposed tension algorithm is robust to disturbance and tension variation. First the modeling and dynamic behaviors of the tension system is described. Then validity and usefulness of the proposed algorithm and mechanical system are thoroughly verified through numerical simulation and actual conditions.
