A new paradigm based on agents applied to free-hand sketch recognition

Important advances in natural calligraphic interfaces for CAD (Computer Aided Design) applications are being achieved, enabling the development of CAS (Computer Aided Sketching) devices that allow facing up to the conceptual design phase of a product. Recognizers play an important role in this field, allowing the interpretation of the user’s intention, but they still present some important lacks. This paper proposes a new recognition paradigm using an agent-based architecture that does not depend on the drawing sequence and takes context information into account to help decisions. Another improvement is the absence of operation modes, that is, no button is needed to distinguish geometry from symbols or gestures, and also “interspersing” and “overtracing” are accomplishedThe Spanish Ministry of Science and Education and the FEDER Funds, through the CUESKETCH project (Ref.

Vision systems with the human in the loop

The emerging cognitive vision paradigm deals with vision systems that apply machine learning and automatic reasoning in order to learn from what they perceive. Cognitive vision systems can rate the relevance and consistency of newly acquired knowledge, they can adapt to their environment and thus will exhibit high robustness. This contribution presents vision systems that aim at flexibility and robustness. One is tailored for content-based image retrieval, the others are cognitive vision systems that constitute prototypes of visual active memories which evaluate, gather, and integrate contextual knowledge for visual analysis. All three systems are designed to interact with human users. After we will have discussed adaptive content-based image retrieval and object and action recognition in an office environment, the issue of assessing cognitive systems will be raised. Experiences from psychologically evaluated human-machine interactions will be reported and the promising potential of psychologically-based usability experiments will be stressed

Fine-Grained Retrieval of Sports Plays using Tree-Based Alignment of Trajectories

We propose a novel method for effective retrieval of multi-agent spatiotemporal tracking data. Retrieval of spatiotemporal tracking data offers several unique challenges compared to conventional text-based retrieval settings. Most notably, the data is fine-grained meaning that the specific location of agents is important in describing behavior. Additionally, the data often contains tracks of multiple agents (e.g., multiple players in a sports game), which generally leads to a permutational alignment problem when performing relevance estimation. Due to the frequent position swap of agents, it is difficult to maintain the correspondence of agents, and such issues make the pairwise comparison problematic for multi-agent spatiotemporal data. To address this issue, we propose a tree-based method to estimate the relevance between multi-agent spatiotemporal tracks. It uses a hierarchical structure to perform multi-agent data alignment and partitioning in a coarse-to-fine fashion. We validate our approach via user studies with domain experts. Our results show that our method boosts performance in retrieving similar sports plays -- especially in interactive situations where the user selects a subset of trajectories compared to current state-of-the-art methods

Methodological Anxiety: Heidegger on Moods and Emotions

In the context of a history of the emotions, Martin Heidegger presents an important and yet challenging case. He is important because he places emotional states, broadly construed, at the very heart of his philosophical methodology—in particular, anxiety and boredom. He is challenging because he is openly dismissive of the standard ontologies of emotions, and because he is largely uninterested in many of the canonical debates in which emotions figure. My aim in this chapter is to identify and critique the distinctive role which Heidegger allots to the emotions, focusing on Sein und Zeit's famous treatment of anxiety. Having outlined his position, I close by considering a number of challenges, both methodological and substantive, to Heidegger's approach

Complexity in city systems: Understanding, evolution, and design

6.4 Exemplars of complex systems There are many signatures of complexity revealed in the space-time patterning of cities (Batty, 2005) and here we will indicate three rather different but nevertheless linked exemplars. Our first deals with ..

Confucian Virtue Jurisprudence

Virtue jurisprudence is an approach to legal theory that develops the implications of virtue ethics and virtue politics for the law. Recent work on virtue jurisprudence has emphasized a NeoAristotelian approach. This essay develops a virtue jurisprudence in the Confucian tradition. The title of this essay, “Confucian Virtue Jurisprudence,” reflects the central aim of our work, to build a contemporary theory of law that is both virtue-centered and that provides a contemporary reconstruction of the central ideas of the early Confucian intellectual tradition. This essay provides a sketch of our contemporary version of Confucian virtue jurisprudence, including a view of (1) the ends of law, (2) legislation and the judiciary, (3) the nature of law. We shall argue that the highest value of Confucian ethical, political theory is the virtue of citizens and the harmony of society and individuals. From the perspective of the use of evaluative language, the Confucian doctrine of Correcting Names gives us an explanation of the mechanism of internalization of legal rules in terms of the relationship among social norms, law and thick evaluative concepts. This might throw light on our normative understanding of legislation and the judiciary,and it also provides a functional account of the nature of law
