Modification of a digital image by adding or removing some of its elements using a wide variety of image processing tools results in image forgery. As a result authentication of originality of a digital image is becoming a challenging task. Copy-paste forgery is one of the forgeries belonging to context based forgery. Copy-Paste Forgery Detection (CPFD) aims at finding regions that have been co...

The Emerging Student Experience What we think of as cutting-edge learning technologies today differ significantly from just a decade ago. Students themselves are changing, too, as their practices are shaped by the technological environment.1 A majority of today's college students would probably not first associate cut-and-paste with scissors and glue; for them technologies like digital cameras ...

which includes the medicine of primitive peoples today, "Ancient Egypt," and "Mesopotamia." A remarkable linguist, Sigerist has used original documents most extensively. Because of language barriers, few other historians in any field could employ as wide a range of sources as Sigerist has. Moreover, he has interpreted his sources in a truly historical manner. Most histories of medicine are of t...

This paper presents the ALOCOM framework for flexible content reuse. Unlike the usual practice where document components, such as images, definitions, text fragments, tables or diagrams, are assembled manually through copy-and-paste, the framework enables on-the-fly access and reuse. Retrieval of relevant components is enabled by automatic decomposition of legacy documents and storage of indivi...

As an undergraduate computer science student, I thought that the main reason to create new routines, instead of leaving all the code in one big routine, was to avoid duplicate code. This is undoubtedly the most popular reason for creating a routine, and it’s a good one. Similar code in two routines is a warning sign. David Parnas says that if you use copy and paste while you’re coding, you’re p...

This paper describes the design and development of new software for spectral analysis, editing and resynthesis. Analysis is accomplished using a variation of the traditional McAulay-Quatieri technique of peak interpolation and partial tracking. Linear prediction of the partial amplitudes and frequencies is used to determine the best continuations for sinusoidal tracks. A high performance user i...

We describe the design and evaluation of a technique aimed at improving text editing on touchscreen devices that exploit the use of stylus-based gestures. The technique has been designed by choosing the most natural gestures for users, established in a preliminary study. The technique allows the user to interact directly with the text to perform commands such as select, move, copy, delete and p...

Consider a natural image that has been manipulated by copying, transforming and pasting back fragments of the image itself. Our goal is to detect such manipulations in the absence of any knowledge about the content of the repeated fragments or the transformations to which they might have been subject. The problem is non-trivial even in the absence of any transformations. For example, copy/paste...

By examining contemporary changes in the mechanisms and practices of representation and communication, this paper focuses on the copy-and-paste affordance fostered by mobile technologies and digital technologies at large. Its widespread use is affecting radically (1) the acceptability standards of (in)coherent patterns of text production, and (2) the criteria defining successful communication, ...

Kaneko-Suzuki developed epistemic logics of shallow depths with multiple players for investigations of game theoretical problems. By shallow depth, we mean that nested occurrences of belief operators of players in formulae are restricted, typically to be of finite depths, by a given epistemic structure. In this paper, we develop various methods of surgical operations (cut and paste) of epistemi...
