Accession number: 20132716474800 Title: Ultrasonic image de-noising based on new wavelet threshold function Authors: Liu, Yan Xia1 ; Han, Bing1 ; Li, Yanu2 ; Dong, Bei Bei1 ; Cao, Yan Yan1 Author affiliation: 1 College of Information Science and Engineering, Hebei North University, Hebei, China 2 Department of Electrical Engineering, Vocational College of Technology, Hebei, China Source title: Applied Mechanics and Materials Abbreviated source title: Appl. Mech. Mater. Volume: 327 Monograph title: Advanced Research on Materials, Applied Mechanics and Design Science Issue date: 2013 Publication year: 2013 Pages: 1641-1644 Language: English ISSN: 16609336 E-ISSN: 16627482 ISBN-13: 9783037857175 Document type: Conference article (CA) Conference name: 2nd International Conference on Intelligent Materials, Applied Mechanics and Design Science, IMAMD 2013 Conference date: April 13, 2013 - April 14, 2013 Conference location: Guangzhou, China Conference code: 97684 Sponsor: International Science and Education Researcher Association, China; Beijing Gireida Education Research Center; VIP-Information Conference Center, China Publisher: Trans Tech Publications Ltd, Kreuzstrasse 10, Zurich-Durnten, CH-8635, Switzerland Abstract: In order to improve the quality of image de-noising,against the disadvantages of the distortion caused by the method of the hard threshold de-noising and the fuzzy phenomenon of the details caused by the method of the soft threshold de-noising, this article proposes a new method of wavelet threshold de-noising for the ultrasonic images. It is indicated in the simulation result that this method has good de-noising function: it can remove the noise effectively and retain the details of the images and the edge information at the same time. © (2013) Trans Tech Publications, Switzerland.
