To reduce the Gibbs phenomenon, Non-subsampled Shearlet Transform (NSST) with the property of shift- invariance was used to decompose source images and get their low-frequency subband and high frequency subband coefficients. Regional variance was used as connection strength factor of the Pulse Coupled Neural Network (PCNN) in the low frequency coefficient fusion, which is more according with human visual characteristics. In the fusion of high frequency coefficients, the Regional Gradient Energy of Direction Information Measure (RGEDIM) was introduced to extract the edge, texture and other details of the image and integrated them into the final image, the impact of noise on image fusion was reduced better. Finally, the fusion image was obtained through NSST inverse transform. The experimental results show that this method is superior to wavelet, Non-subsampled Contourlet Transform (NSCT) and traditional PCNN method, the fusion image has more mutual information and contains more original image information, all the defects of the source image can be clearly seen on the fusion image.<\/jats:p>","DOI":"10.3233\/jcm-204406","type":"journal-article","created":{"date-parts":[[2020,7,21]],"date-time":"2020-07-21T14:31:00Z","timestamp":1595341860000},"page":"329-339","source":"Crossref","is-referenced-by-count":1,"title":["Composite material terahertz image fusion based on PCNN and RGEDIM under non-subsampled shearlet transform"],"prefix":"10.1177","volume":"21","author":[{"given":"Fu","family":"Liu","sequence":"first","affiliation":[]},{"given":"Yifan","family":"Liao","sequence":"additional","affiliation":[]}],"member":"179","reference":[{"key":"10.3233\/JCM-204406_ref1","first-page":"1","article-title":"Determination of strength parameters of glass fibers reinforced composites for engineering applications","volume":"1","author":"Muralidhar Singh","year":"2019","journal-title":"Silicon"},{"issue":"4","key":"10.3233\/JCM-204406_ref2","doi-asserted-by":"crossref","first-page":"361","DOI":"10.1080\/10589759.2018.1484921","article-title":"Evaluation of three nondestructive testing techniques for quality assessment of asphalt pavements","volume":"33","author":"Shibin","year":"2018","journal-title":"Nondestructive Testing and Evaluation"},{"issue":"127","key":"10.3233\/JCM-204406_ref4","first-page":"67","article-title":"Nondestructive evaluation of rubber composites using terahertz time domain spectroscopy","volume":"Nr1","author":"Xu","year":"2018","journal-title":"Fibres & Textiles in Eastern Europe"},{"issue":"15","key":"10.3233\/JCM-204406_ref5","doi-asserted-by":"crossref","first-page":"338","DOI":"10.1016\/j.compstruct.2015.09.055","article-title":"Nondestructive evaluation of hidden multi-delamination in a glass-fiber-reinforced plastic composite using terahertz spectroscopy","volume":"156","author":"Ryua","year":"2016","journal-title":"Composite Structures"},{"issue":"4","key":"10.3233\/JCM-204406_ref6","doi-asserted-by":"crossref","first-page":"866","DOI":"10.1109\/TMM.2017.2760100","article-title":"Multisensor image fusion and enhancement in spectral total variation domain","volume":"20","author":"Zhao","year":"2017","journal-title":"IEEE Transactions on Multimedia"},{"issue":"8","key":"10.3233\/JCM-204406_ref7","doi-asserted-by":"crossref","first-page":"1977","DOI":"10.1007\/s00500-015-1893-0","article-title":"Image fusion by combining multi-wavelet with nonsubsampled direction filter bank","volume":"21","author":"Geng","year":"2017","journal-title":"Soft Computing"},{"key":"10.3233\/JCM-204406_ref8","doi-asserted-by":"crossref","unstructured":"A.L.
