Planogram Compliance Checking Based on Detection of Recurring Patterns

In this paper, a novel method for automatic planogram compliance checking in retail chains is proposed without requiring product template images for training. Product layout is extracted from an input image by means of unsupervised recurring pattern detection and matched via graph matching with the expected product layout specified by a planogram to measure the level of compliance. A divide and conquer strategy is employed to improve the speed. Specifically, the input image is divided into several regions based on the planogram. Recurring patterns are detected in each region respectively and then merged together to estimate the product layout. Experimental results on real data have verified the efficacy of the proposed method. Compared with a template-based method, higher accuracies are achieved by the proposed method over a wide range of products.Comment: Accepted by MM (IEEE Multimedia Magazine) 201

Scraping Down the Past: Memory and Amnesia in W. G. Sebald\u27s Anti-narrative

Vanguard anti-narrativist Galen Strawson declares personal memory unimportant for self-constitution. But what if lapses of personal memory are sustained by a morally reprehensible amnesia about historical events, as happens in the work of German author W. G. Sebald? The importance of memory cannot be downplayed in such cases. Nevertheless, contrary to expectations, a concern for memory needn’t ally one with the narrativist view of the self. Recovery of historical and personal memory results in self-dissolution and not self-unity or understanding in Sebald’s characters. In the end, Sebald shows how memory can be significant, even imperative, within a deeply anti-narrativist outlook on the self, memory, and history

Reconsidering "the love of art" : evaluating the potential of art museum outreach

Art museums have long been identified as bastions of social and cultural exclusion. This conclusion was best evidenced by the large-scale 1967 French study by Bourdieu and Darbel demonstrating the exclusionary nature of “The Love of Art.” However, in recent years there have been increasing efforts to reach out to a broader range of visitors beyond conventional audiences. The present study investigates the impacts of an outreach program at a UK art museum, which sought to engage socially excluded young mothers. This study employs ethnographic research methods on a longitudinal basis to develop qualitative insights about the program seeking to mitigate cultural exclusion. While the study’s findings uphold many longstanding critiques of art museums’ conventional approaches, the study also indicates that carefully designed outreach activities can overcome such limitations and enhance cultural engagement. Thus, art museums’ limited appeal is tied to problematic public engagement practices that can be changed

X-ray variability with WFXT: AGNs, transients and more

The Wide Field X-ray Telescope (WFXT) is a proposed mission with a high survey speed, due to the combination of large field of view (FOV) and effective area, i.e. grasp, and sharp PSF across the whole FOV. These characteristics make it suitable to detect a large number of variable and transient X-ray sources during its operating lifetime. Here we present estimates of the WFXT capabilities in the time domain, allowing to study the variability of thousand of AGNs with significant detail, as well as to constrain the rates and properties of hundreds of distant, faint and/or rare objects such as X-ray Flashes/faint GRBs, Tidal Disruption Events, ULXs, Type-I bursts etc. The planned WFXT extragalactic surveys will thus allow to trace variable and transient X-ray populations over large cosmological volumes.Comment: Proceedings of "The Wide Field X-ray Telescope Workshop", held in Bologna, Italy, Nov. 25-26 2009 (arXiv:1010.5889).

IR theory, historical materialism, and the false promise of international historical sociology

The three-decades old call for an inter-disciplinary rapprochement between IR Theory and Historical Sociology, starting in the context of the post-positivist debate in the 1980s, has generated a proliferating repertory of contending paradigms within the field of IR, including Neo-Weberian, Post-Structuralist, and Constructivist approaches. Within the Marxist literature, this project comprises an equally rich and diverse set of theoretical traditions, including World-Systems Theory, Neo-Gramscian IR/IPE, the Amsterdam School, Political Marxism, Neo-Leninism, and Postcolonial Theory. More recently, a “third wave” of approaches has been announced from within the field of IR, suggesting to move the dialogue from inter-disciplinarity towards an integrated super-discipline of International Historical Sociology (IHS). This proposition has been most persistently advanced by advocates of the theory of Uneven and Combined Development (UCD), claiming to constitute a universal, unitary and sociological theory of IR. This article charts the intellectual trajectory of this ongoing IR/HS dialogue. It moves from a critique of Neo-Weberianism to a critique of UCD against the background of the original promise of the turn in IR to Historical Sociology: the supersession of the prevailing rationalism, structuralism, and positivism in extant mainstream IR approaches through the mobilization of alternative and non-positivistic traditions in the social sciences. This critique will be performed by setting UCD in dialogue with Political Marxism. By anchoring both approaches at opposite ends on the spectrum of Marxist conceptions of social science – respectively the scientistic and the historicist - the argument is that UCD reneges on the promise of Historical Sociology for IR by re-aligning, first by default and now by design, with the meta-theoretical premises of Neo-Realism. This is most visibly expressed in the articulation of a deductive-nomological covering law, leading towards acute conceptual and ontological anachronisms, premised on the radical de-historicisation of the fields of ontology, conceptuality and disciplinarity. This includes the semantic neutering and hyper-abstract re-articulation of the very category, which in IR’s self-perception lends legitimacy to its claim of disciplinary distinctiveness: the international. The article concludes by suggesting that an understanding of Marxism as a historicist social science subverts all calls for the construction of grand theories and, a fortiori, a unitary super-discipline of IHS, premised on a set of universal, space-time indifferent, and abstract categories that hold across the spectrum of world history. In contrast, recovering the historicist credentials of Marxism demands a constant temporalisation and specification of the fields of ontology, agency, conceptuality and disciplinarity. The objective is to lay the foundations for a historicist social science of geopolitics

Musical Thought And Compositionality

Many philosophers and music theorists have claimed that music is a language, though whether this is meant metaphorically or literally is often unclear. If the claim is meant literally, then it faces serious difficulty—many find it compelling to think that music cannot be a language because it lacks any semantic value. On the other hand, if it is meant metaphorically, then it is not clear what is gained by the metaphor—it is not clear what the metaphor is meant to illuminate. Considering the claim as a metaphor, I take it that what a theorist who speaks in this way is trying to draw our attention to is that there are interesting and illuminating parallels between music and language that might be philosophicallysignificant. Ifthisistheirpoint,thenthequestionis:whatinteresting parallel is it that could be so philosophically significant

Analysis and intuition in strategic decision making. The case of California

Many management scholars believe that the process used to make strategic decisions affects the quality of those decisions. However several authors have observed a lack of research on the strategic decision making process. Empirical tests of factors that have been hypothesized to affect the way strategic decisions are made notably are absent. (Fredrickson, 1985) This paper reports the results of a study that attempts to assess the effects of decision making circumstances focusing mainly on the approaches applied and the managerial skills and capabilities the decision makers built on during concrete strategic decision making procedures. The study was conducted in California between September 2005 and June 2006 and it was sponsored by a Fulbright Research Scholarship Grant
