明代文言小说《西京杂记》《续巳编》为伪书考

《西京杂记》《续巳编》为明代隆庆年间刊行的文言小说,题杨穆、郎瑛著。目前可知此二书最早见于《类编古今名贤汇语》丛书,后又被节录、收入《说郛续》。明后期特别是入清以来,《说郛续》本被诸家书志沿录、注引不辍,然此二书之性质实大有问题。笔者今据国家图书馆藏明刻本《今贤汇说》《类编古今名贤汇语》,考证《西京杂记》《续巳编》为伪书。希望可以订正相关著录。     

志怪小说韵文谫论

学界迄今未有关于志怪小说韵文方面的专门论著。志怪小说中的韵文体量较小,在不同时期有着不同的文体形式和思想内容;其成因与韵散结合的文学传统,所处时代的学术、思想和创作思潮,以及作者的文化学养和创作雅尚都紧密相关;其艺术水平、文献价值和小说功能总体上相对平庸。志怪小说的文体特征决定了其韵文承载能力的先天不足。     

Multiframe blind super resolution imaging based on blind deconvolution

As an ill-posed problem, multiframe blind super resolution imaging recovers a high resolution image from a group of low resolution images with some degradations when the information of blur kernel is limited. Note that the quality of the recovered image is influenced more by the accuracy of blur estimation than an advanced regularization. We study the traditional model of the multiframe super resolution and modify it for blind deblurring. Based on the analysis, we proposed two algorithms. The first one is based on the total variation blind deconvolution algorithm and formulated as a functional for optimization with the regularization of blur. Based on the alternating minimization and the gradient descent algorithm, the high resolution image and the unknown blur kernel are estimated iteratively. By using the median shift and add operator, the second algorithm is more robust to the outlier influence. The MSAA initialization simplifies the interpolation process to reconstruct the blurred high resolution image for blind deblurring and improves the accuracy of blind super resolution imaging. The experimental results demonstrate the superiority and accuracy of our novel algorithms.
