Springs-based Simulation for Image Retargeting
2011
In this paper an efficient method for image retargeting is pro- posed. It relies onto a mechanical model based on springs network. Each pixel displacement (compression or expan- sion) is given by the network response, according to the springs stiffness. The properties of the springs are deter- mined as function of the visual relevance of the pixels. Such model does not require any optimization, since its so- lution is obtained simply from a linear system of equations, allowing real-time application even for large images. The approach is fully automatic, though can be improved by interactively providing cues such as geometric constraints and/or manual relevant object labeling. The results pr…
Real-time content-aware image resizing using reduced linear model
2010
In this paper an effective and efficient method for contentaware image resizing is proposed. It is based on the solution of a linear system where each pixel displacement (compression or expansion) is determined in dependence of the visual relevance of the pixel itself. The linear nature of the model allows real-time application of the method even for large images. This fully automatic approach can be also improved by interactively providing cues such as geometric constraints and/or manual relevant object labeling. The results have proven that the presented method achieves results comparable or superior to existent strategies, while improving efficiency.
Retargeting Framework Based on Monte-carlo Sampling
2015
Advance in image technology and proliferation of acquisition devices like smartphones, digital cameras, etc., made the display of digital images ubiquitous. Many displays exist in the market, spanning within a large variety of resolutions and shapes. Thus, displaying content optimizing the available number of pixels has become a very important issue in the multimedia community, and the image retargeting problem is being widely faced. In this work, we propose an image retargeting framework based on monte-carlo sampling. We operate the non-homogeneous resizing as the composition of several simple atomic resizing functions. The shape of such atomic operator can be chosen within a set of tested…
Responsibility in uncertain times: an institutional perspective on precaution
2008
Precaution is a key issue in environmental governance. Variously defined, intensively debated and introduced in many regulations, its meaning, scope and application remain problematic. This article argues that the controversy on precaution is a matter of culturally patterned expectations concerning the production and use of knowledge and the related social positions and responsibilities. The way uncertainty and its role in the policy process are understood is crucial. For some precaution is a flawed concept, to be accommodated to the current expert-based cooperative scheme. For others it is a major innovation requiring a rearrangement of the latter. Precautionary policies may evolve in dif…
“Nos inventamos un mundo que no existía”. Una profesión de riesgo.
2019
Since the end of Franco's dictatorship, editorial censorship has been an object of interdisciplinary study that has been incorporating, to the initial analysis of the constitution and nature of censorship, the study of a variety of case studies that are resizing the phenomenon. On the one hand, in the context of memory studies, it is necessary to analyze what effects censorship had on the configuration of cultural memory. On the other hand, censorship has a considerable effect on publishing strategies, both in itself and because it fosters self-censorship and countercensorship. In particular, this article explores the work of women publishers who, in the Barcelona of the 1960s and 1970s, op…
EU Referenda in the Baltics: Understanding the Results at the Regional Level
2005
This paper analyses regional differences in EU referenda results in Estonia, Latvia, and Lithuania. In each of the three countries, other things being equal, high income regions were significantly more pro-European than low-income ones, while regions with a high share of ethnic minorities were significantly more opposed to the enlargement than other regions. The ethnic effect was strongest in Latvia and weakest in Estonia. These findings clearly indicate necessity of stronger efforts both in integration of the Baltic societies and in the promotion of reliable EU information, especially in less developed regions. On the other hand, we confirm the findings from earlier referenda that support …
Mobility of Cultures and Knowledge Management in Contemporary Europe
2012
In the aftermath of the fall of the Iron Curtain, the European Union (EU) has included more and more new member states from Central and Eastern parts of the European continent. This enlargement process has increased the cultural diversity of the European community as new languages and minority groups have been subsumed into the EU. It is the purpose of this article to discuss the challenges that result from the EU's enlargement, together with the added intra-European mobility of cultures, that affect the national knowledge infrastructures. Based on recent social scientific scholarship on mobility and cultures, this article proposes that knowledge management in contemporary Europe is not onl…
