Split Bregman algorithms for multiple measurement vector problem ×÷Õß:Zou, J (Zou, Jian)[ 2,1 ] ; Fu, YL (Fu, Yuli)[ 2 ] ; Zhang, QH (Zhang, Qiheng)[ 2 ] ; Li, HF (Li, Haifeng)[ 2 ] MULTIDIMENSIONAL SYSTEMS AND SIGNAL PROCESSING ¾í: 26 ÆÚ: 1 Ò³: 207-224 DOI: 10.1007/s11045-013-0251-6 ³ö°æÄê: JAN 2015 ²é¿´ÆÚ¿¯ÐÅÏ¢ ÕªÒª The standard sparse representation aims to reconstruct sparse signal from single measurement vector which is known as SMV model. In some applications, the SMV model extend to the multiple measurement vector (MMV) model, in which the signal consists of a set of jointly sparse vectors. In this paper, efficient algorithms based on split Bregman iteration are proposed to solve the MMV problems with both constrained form and unconstrained form. The convergence of the proposed algorithms is also discussed. Moreover, the proposed algorithms are used in magnetic resonance imaging reconstruction. Numerical results show the effectiveness of the proposed algorithms. ¹Ø¼ü´Ê ×÷Õ߹ؼü´Ê:Multiple measurement vector problem; Split Bregman iteration; Convergence; MRI reconstruction KeyWords Plus:SIMULTANEOUS SPARSE APPROXIMATION; RANK AWARENESS; MR-IMAGES; RECONSTRUCTION; RECOVERY ×÷ÕßÐÅÏ¢ ͨѶ×÷ÕßµØÖ·: Fu, YL (ͨѶ×÷Õß) ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ S China Univ Technol, Sch Elect & Informat Engn, Guangzhou 510641, Guangdong, Peoples R China. µØÖ·: [ 1 ] Yangtze Univ, Sch Informat & Math, Jinzhou 434020, Hubei, Peoples R China ÏÔʾÔöÇ¿×éÖ¯ÐÅÏ¢µÄÃû³Æ [ 2 ] S China Univ Technol, Sch Elect & Informat Engn, Guangzhou 510641, Guangdong, Peoples R China µç×ÓÓʼþµØÖ·:zoujianjz@gmail.com; fuyuli@scut.edu.cn; qiheng.zhang@gmail.com; lihaifengxx@126.com »ù½ð×ÊÖúÖÂл »ù½ð×ÊÖú»ú¹¹ ÊÚȨºÅ International cooperation project of Guangdong Natural Science Foundation 2009B050700020 NSFC-Guangdong Union Project U0835003 NSFC 60903170 61004054 61104053 61103122 ²é¿´»ù½ð×ÊÖúÐÅÏ¢ ³ö°æÉÌ SPRINGER, VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS Àà±ð / ·ÖÀà Ñо¿·½Ïò:Computer Science; Engineering Web of Science Àà±ð:Computer Science, Theory & Methods; Engineering, Electrical & Electronic ÎÄÏ×ÐÅÏ¢ ÎÄÏ×ÀàÐÍ:Article ÓïÖÖ:English Èë²ØºÅ: WOS:000347953000012 ISSN: 0923-6082 eISSN: 1573-0824 ÆäËûÐÅÏ¢ IDS ºÅ: AZ0RT Web of Science ºËÐĺϼ¯ÖÐµÄ "ÒýÓõIJο¼ÎÄÏ×": 33 Web of Science ºËÐĺϼ¯ÖÐµÄ "±»ÒýƵ´Î": 0 |
