Detection of Bobbin Yarn Surface Defects by Visual Saliency Analysis
Junfeng Jing,Haiye Li,Huanhuan Zhang,Zebin Su,Kaibing Zhang 한국섬유공학회 2020 Fibers and polymers Vol.21 No.11
In order to solve the problem of unstable quality of the traditional bobbin yarn surface defect detection, a methodfor detecting the surface defect of bobbin yarn using visual saliency analysis is proposed. Firstly, the Difference of Gaussianalgorithm is used to suppress the texture of the image, and the contrast between the defect area and the background isenhanced. Then, the method of wavelet threshold is applied to filter the noise in the images after the Difference of Gaussian,and the detailed features of the defect area are preserved while the noise interference is eliminated. Finally, the frequencytuned visual saliency algorithm is used to extract and segment the defective regions accurately. After the process about theDifference of Gaussian and wavelet threshold denoising, the original image of the bobbin yarn can make the image highlightthe feature information of the defect area on the basis of ensuring elimination of the background texture and noise, andfacilitate the detection of the defect area by combining visual saliency analysis. In the detection of the accuracy and integrityof the defect area, the detection method of this paper is better than the control method, and the defect segmentation result ismore accurate. The proposed method for detecting the surface defect of the bobbin can not only completely eliminate theinfluence of the background texture of the bobbin surface, but also accurately and completely detect the surface defect of thebobbin, and the defect details remain intact. In this paper, the effectiveness of the algorithm is further verified by objectivetests. The precision and recall rate of the test are 95.15 % and 98.00 %, respectively, which can meet the needs of actualdetection.

Background: The biophysical properties of the meridian system, an important concept of traditional Chinese medicine, include low impedance, resounding voice, and high acoustic conductance, all of which are helpful for elucidating the essence of meridians. Objectives: To visualize the human pericardium meridian (PC) based on the resounding voice property of meridians. Methods: Visualization of the PC was performed by injection of fluorescein sodium at the PC6 acupoint (Neiguan) on the PC. Before injection, percussion active points (PAPs) were identified by the virtue of their resounding voice properties. After injection, the trajectories of fluorescein migration throughout the body surface were recorded and analyzed. The distribution of fluorescein in the tissue was further studied using cross-sections of hind limbs of mini-pigs, in which fluorescein was injected into low impedance points. Results: The identified PAP lines were colocalized with PC. Following intradermal fluorescein injection, 1-3 fluorescent lines, which were unrelated to the arm veins, were observed in 7 of 10 participants; 85.4% of fluorescent signals were coincident with PAPs and their intensity had a negative correlation with the body mass index (r = –0.56, p = 0.045). Cross-sections showed a Y-shaped fluorescence pattern where the two migration lines on the surface were the two vertices of the “Y.” Conclusion: The trajectories of fluorescein in the body are suggestive of the anatomical structure of meridians. The PC is related to the deep horizontal interstitial channels that connect to the body surface through vertical interstitial spaces. These biophysical properties and techniques for meridian visualization are valuable for revealing the anatomical structure of meridians.
