In the era of digital technology, it becomes easy to share photographs and videos using smartphones and social networking sites to their loved ones. On the other hand, many photo editing tools evolved to make it effortless to alter multimedia content. It makes people accustomed to modifying their photographs or videos either for fun or extracting attention from others. This altering brings a questionable validity and integrity to the kind of multimedia content shared over the internet when used as evidence in Journalism and Court of Law. In multimedia forensics, intense research work is underway over the past two decades to bring trustworthiness to the multimedia content. This paper proposes an efficient way of identifying the manipulated region based on Noise Level inconsistencies of spliced mage. The spliced image segmented into irregular objects and extracts the noise features in both pixel and residual domains. The manipulated region is then exposed based on the cosine similarity of noise levels among pairs of individual objects. The experimental results reveal the effectiveness of the proposed method over other state-of-art methods.

In this classroom research project, 27 learners in three courses at one university use professional-level, photo-editing software to create and remix images in language lessons. The overarching purpose of this study is to deepen understanding of what actually occurs in lessons through the use of materials. I delivered these lessons with a Content and Language Integrated Learning approach in which English was used for both the teaching and learning of not only lesson content but also language (Coyle, Hood, & Marsh, 2010). Data include emails written by the learners to describe and evaluate their experiences with the software, digital artifacts created during the courses, and my research journal. Qualitative analysis is conducted in a grounded fashion using iterative coding (Saldaña, 2013) to identify emergent themes from a research perspective of materials use. Learners appear to demonstrate self-direction and creativity in highly personal ways throughout the lessons. 本授業調査研究では、ある大学における3つのコースにおいて、27人の学習者が専門家レベルの写真編集ソフトウェアを使用し、語学の授業内で画像の作成およびリミックスを行った。この研究の包括的な目的は、学習者にこれら諸教材を用いることにより授業中に起こることを深く理解させることである。本研究指導者は、授業内容だけでなく言語教育と学習の両方に英語を使用するContent and Language Integrated Learning(内容言語統合型学習)によるアプローチを用いた (Coyle, Hood, & Marsh, 2010)。データには、ソフトウェアを用いた経験を説明および評価するために学習者が書いた電子メール、コース中に作成したデジタルアーティファクト、および指導者が所持する研究ジャーナルを含む。質的分析には、教材使用の研究展望から生まれてくるテーマを特定するために反復コーディング (Saldaña, 2013)を用いた。学生はレッスンを通じ、自分なりのやり方で自己主導性と創造性を示した。

Figures for scientific publications go through various stages from the planning, to the capturing of images, to the production of finished figures for publication. This guide is meant to familiarise the reader with the main image-editing software used by professional photographers. The guide’s focus is on digital photo editing and the production of figures using Adobe Photoshop to produce publication-quality figures for scientific publications. This guide will be of fundamental use for the academic public, especially taxonomists and others who work with images. Besides, it should be useful for anyone interested in becoming familiar with the basic tools of image editing.

To investigate peoples' trait attribution biases, we asked participants to generate faces of "bad guys" and "good guys" using three methods: free drawings, photo-editing, and feature assembly. In referring to research linking facial width (relative to height, fWHR) with aggressive and dominant personality traits in males, we compared fWHR displayed in the generated portraits between the two character types . We found that participants modelled emotional expressions (in particular, expression of anger and fear/friendliness), but not fWHR per se, to portray character trait. When emotional expressions were statistically controlled for, no difference in fWHR between "bad guys" and "good guys" remained. We conclude that emotion overgeneralization is a strong confound in research on fWHR.

IT-ASSIST is a twenty months research project which has the goal to give elderly people the opportunity to profit from digital media. Suffering from age related impairments concerning vision, hearing, or dexterity and bad hand-eye coordination are challenges when designing user interfaces for elderly people. Common approaches are trying to model systems for specific impairments. In this project, the authors follow the approach to set up interfaces and systems that can be used independent from personal impairments. Customization has adapted these systems to be in accordance with personnel impairments. Common applications like photo editing, digital mailing or internet browsing in a redesigned form provide social communication accordingly. In this article, a prototype of a customized user interface, its implementation, and results of user studies are presented and discussed.

Subgrain structures are frequently characterized by the electron backscatter diffraction (EBSD) method, which is both accurate and provides good statistics. This is essential to better understand the subgrain growth mechanisms and e.g. establish the driving forces and motilities for comparison with physically based models. However, there is no commercially available software which can provide adequate subgrain boundary maps necessary for e.g. size and misorientation analysis. Here, a method that produces such maps utilizing only commercially available software is presented. The clue is to provide the EBSD-software with a parameter that can be used to identify all subgrains. By combining various maps exported from the EBSD-software into photo editing software, a new map is made in which all subgrain boundaries are identified. Missing and incomplete boundaries are traced manually before a reconstructed subgrain map is generated and imported back into the EBSD-software. With this method, the built-in algorithms in the EBSD-software can be readily used to e.g. characterize subgrain growth in aluminium with respect to orientation, size and misorientation.
