Brinkkemper, O. (author), Van der Maaten, L.J.P. (author), Boon, P. (author)Despite their name, the identification of seeds of Myosotis species (forget-me-not) has hitherto received little attention from archaeobotanists. In an attempt to assemble a collection of reliable identification criteria, digital image analysis was applied to photographs of Myosotis seeds by means of Fovea Pro 4.0. This program computes 23...journal article 2011

(author), Van Walsum, T. (author), Niessen, W.J. (author)Cardiac magnetic resonance perfusion imaging (CMR) and computed tomography angiography (CTA) are widely used to assess heart disease. CMR is used to measure the global and regional myocardial function and to evaluate the presence of ischemia; CTA is used for diagnosing coronary artery disease, such as coronary stenoses. Nowadays, the hemodynamic...conference paper 2011

Koenderink, J. (author)The egg-rolling behavior of the graylag goose is an often quoted example of a fixed-action pattern. The bird will even attempt to roll a brick back to its nest! Despite excellent visual acuity it apparently "takes a brick for an egg." Evolution optimizes utility, not veridicality. Yet textbooks take it for a fact that human vision evolved so as...conference paper 2011

Busking, S. (author), Botha, C.P. (author), Ferrarini, L. (author), Milles, J. (author), Post, F.H. (author)Nested or intersecting surfaces are proven techniques for visualizing shape differences between static 3D objects (Weigle and Taylor II, IEEE Visualization, Proceedings, pp. 503–510, 2005). In this paper we present an image-based formulation for these techniques that extends their use to dynamic scenarios, in which surfaces can be manipulated or...journal article 2010

Behrens, T.M. (author), Hindriks, K.V. (author), Dix, J. (author)We introduce an interface for connecting agent platforms to environments. This interface provides generic functionality for executing actions and for perceiving changes in an agent’s environment. It also provides support for managing an environment, e.g., for starting, pausing and terminating it. Among the benefits of such an interface are (1)...journal article 2010

(author)It remains a challenge with current state of the art technology to use BDI agents to control real-time, dynamic and complex environments. We report on our effort to connect the GOAL agent programming language to the real-time game UNREAL TOURNAMENT 2004. We focus in particular on the design of a suitable interface to manage agent-bot interaction...conference paper 2010

(author)Purpose Using three publicly available small-animal atlases (Sprague–Dawley rat, MOBY, and Digimouse), we built three articulated atlases and present several applications in the scope of molecular imaging. Procedures Major bones/bone groups were manually segmented for each atlas skeleton. Then, a kinematic model for each atlas was built: each...journal article 2010

Rothkrantz, L.J.M. (author), Datcu, D. (author)In recent years many systems for distance learning have been developed. Even though students have access to learning material any time and any place, current tools for e-learning still have their limitations. The main shortcoming, compared to real life learning is the limited opportunity for human like interaction between student, teacher and...journal article 2010

Tsikrika, T. (author), Diou, C. (author), De Vries, A.P. (author), Delopoulos, A. (author)Automatic image annotation using supervised learning is performed by concept classifiers trained on labelled example images. This work proposes the use of clickthrough data collected from search logs as a source for the automatic generation of concept training data, thus avoiding the expensive manual annotation effort. We investigate and...journal article 2010

Hofstede, G.J. (author), Jonker, C.M. (author), Verwaart, T. (author)Negotiations proceed differently across cultures. For realistic modeling of agents in multicultural negotiations, the agents must display culturally differentiated behavior. This paper presents an agent-based simulation model that tackles these challenges, based on Hofstede’s model of national cultures. The context is a trade network for goods...journal article 2010

Hindriks, K.V. (author), Tykhonov, D. (author), De Weerdt, M.M. (author)When there is one buyer interested in obtaining a service from one of a set of sellers, multi-attribute or multi-issue auctions can ensure an allocation that is efficient. Even when there is no transferable utility (e.g., money), a recent qualitative version of the Vickrey auction may be used, the QVA, to obtain a Pareto-efficient outcome where...journal article 2010
