IDENTIFICATION OF INPAINTED IMAGES AND NATURAL IMAGES FOR DIGITAL FORENSICS

Image forensics is a form of image analysis for finding out the condition of an image in the complete absence of any digital watermark or signature.It can be used to authenticate digital images and identify their sources.While the technology of exemplar-based inpainting provides an approach to remove objects from an image and play visual tricks.In this paper, as a first attempt, a method based on zero-connectivity feature and fuzzy membership is proposed to discriminate natural images from inpainted images.Firstly, zero-connectivity labeling is applied on block pairs to yield matching degree feature of all blocks in the region of suspicious, then the fuzzy memberships are computed and the tampered regions are identified by a cut set.Experimental results demonstrate the effectiveness of our method in detecting inpainted images.

《艾玛》儒家伦理指向及意义发覆

未刊本英文传记文献《艾玛》生成于一个儒家伦理与西方现代伦理对峙的特殊时期。全书运用自传加评传的手法,记录了艾玛近百年的生命辙迹,尤其是借助一系列限制性和表现性的社会符码和惯例,论述了艾玛宣教于中国西南汉地期间的经验和感觉到的儒家孝道和纲常伦理事象。检视艾玛事关儒家伦理的论述逻辑与形象意义,既能照见儒家伦理的某些缺憾,更能洞见审视者性别身份和价值秩序的影子。从而,不仅有着揭示了世界本身“部分的真理”的价值,而且体现出了“任何‘他者’的版本都同时是‘自我’的建构”的真精神。
