Abstract

This article introduces a method which adopts the computer image manipulation to process the collected images of yarn
black.Aiming at the hairiness and scratches existing in the yarn blackboard, we adopt the methods such as smoothness
processing, threshold value division and image repairing to obtain a clear digital image without yawp points and exactly
measure the yarn diameter. Comparing with the actual yarn diameter, the computed yarn diameter accords with the actual
diameter, which proves that the yarn diameter measured by image processing method is accurate, exactly reflects the
appearance features of the yarn such as slubs, neps and nips, and establishes the foundation for the automatic assessment of the yarn blackboard.
