吴诗 《学位与研究生教育》1997,(4):16-18
为了提高研究生培养质量，导师应选择属于本门学科的前沿领域、特别是其中与四化建设密切结合或迫切需要的前沿领域作为研究生的研究方向。研究工作不但应进入学科前沿，而且要形成自己的研究特色。要在引导研究生增强创新意识的同时，结合研究生的研究课题，不断培养他们从事创新的具体方法。在研究工作中，充分发扬民主，创造自由讨论的学术气氛，使研究生的创造性充分发挥出来。全面贯彻因材施教，根据培养方案，注意调整研究生的知识结构。对研究生在平时研究工作中暴露出来的反映学习态度和学风方面的问题，要严格要求，结合研究工作予以正确引导与教育 相似文献

To extract region of interests (ROI) in brain magnetic resonance imaging (MRI) with more than two objects and improve the segmentation accuracy, a hybrid model of a kernel-based fuzzy c-means(KFCM) clustering algorithm and Chan-Vese (CV) model for brain MRI segmentation is proposed. The approach consists of two successive stages. Firstly, the KFCM is used to make a coarse segmentation, which achieves the automatic selection of initial contour. Then an improved CV model is utilized to subdivide the image. Fuzzy membership degree from KFCM clustering is incorporated into the fidelity term of the 2-phase piecewise constant CV model to obtain accurate multi-object segmentation. Experimental results show that the proposed model has advantages both in accuracy and in robustness to noise in comparison with fuzzy c-means (FCM) clustering, KFCM, and the hybrid model of FCM and CV on brain MRI segmentation. 相似文献

An image fusion method combining complex contourlet transform(CCT) with nonnegative matrix factorization(NMF) is proposed in this paper.After two images are decomposed by CCT,NMF is applied to their highand low-frequency components,respectively,and finally an image is synthesized.Subjective-visual-quality of the image fusion result is compared with those of the image fusion methods based on NMF and the combination of wavelet /contourlet /nonsubsampled contourlet with NMF.The experimental results are evaluated quantitatively,and the running time is also contrasted.It is shown that the proposed image fusion method can gain larger information entropy,standard deviation and mean gradient,which means that it can better integrate featured information from all source images,avoid background noise and promote space clearness in the fusion image effectively. 相似文献
