    Self-reported behavioral data is used in many studies, but lack of accuracy may invalidate conclusions. A study on user guidance mechanisms demonstrates how subject responses differ significantly from the data collected through system logs. Indications are that data collection via observation, logs, or formal records may be worth the extra time and expense View full abstract»

    This paper tackles an important problem in image processing; that is, the detection of edges in natural scenes. A scheme that combines simplicity with the ability to detect intensity jumps at widely varying contrasts is proposed. The scheme is constructed by combining the Laplacian-of-Gaussian (LoG) edge detector with a noise removal mechanism. The mechanism is built around a proposed definition f... View full abstract»

    In the area of artificial neural networks, the concept of combining multiple networks has been proposed as a new direction for the development of highly reliable neural network systems. The authors propose a method for multinetwork combination based on the fuzzy integral. This technique nonlinearly combines objective evidence, in the form of a fuzzy membership function, with subjective evaluation ... View full abstract»

    In many complex problems a particular decision making procedure is often required in order for a final solution to be found. Such a procedure may consist of a large number of intermediate steps where “local” decisions must be taken and can be sometimes represented as a decision tree. When that structure is used the final solutions obtained vary depending on the available information. H... View full abstract»

    An artificial intelligence approach to planning the robotic assembly of large tetrahedral truss structures is presented. Based on the computational formalism known as production system, the approach exploits the simplicity and uniformity of the shapes of the parts and the regularity of their interconnection to drastically reduce the required geometric reasoning computation. The global database con... View full abstract»

    A model-based technique addressing the effect of display or visual scene quality upon human pilot dynamics is introduced. The technique builds upon a methodology proposed for the preliminary assessment of flight simulator fidelity which uses a structural model of the human pilot. This model is incorporated in what is termed the primary control loop(s) for the task at hand. It is shown that the mea... View full abstract»

  • A new safe-point thinning algorithm based on the mid-crack code tracing

    A new thinning algorithm for binary images, based on the safe-point testing and mid-crack code tracing, is presented. Thinning is treated as the deletion of nonsafe border pixels from the contour to the center of the object layer-by-layer. The deletion is determined by masking a 3×3 weighted template and by the use of lookup tables. The resulting skeleton does not require cleaning or pruning... View full abstract»

    A novel approach to the design of training methodologies or programs for operators in man-machine systems and its application to the training of skilled human teleoperators is described. This approach requires that training goals are separated into four distinct categories: the maximization of performance consistency or reliability for critical tasks, the maximization of positive transfer between ...

    In this paper, a new technique for generating fuzzy rules for pattern classification is discussed. First, separation hyperplanes for classes are extracted from a trained neural network. Then, for each class, convex existence regions in the input space are approximated by shifting these hyperplanes in parallel using the training data set for the classes. Using fuzzy rules defined for each class, in... View full abstract»

    Mathematical modeling systems are an important component in the toolkit of decision support system (DSS) generators. These systems provide a language in which mathematical models can be stated, and enable access to algorithms which may be used to manipulate (e.g., optimize, what-if analysis) the model. While these features are useful, we believe that these systems should also support other importa... View full abstract»

    This paper addresses the problem of predicting the path of a vehicle performing a transit mission. Such a mission proceeds from a start location to a goal location guided by an intelligent planning strategy. Given the history of a path from a start location to a current location, the objectives are: 1) to estimate the cost criterion guiding the travel; 2) to predict the goal location; and 3) to pr...

    In a distributed system, a group of agents have a potential for improved performance depending on their ability to utilize shared resources. This potential synergy raises the question of whether agents should work together in a system-wide group, i.e., a coalition, or whether they should work alone. In general, there is uncertainty as to whether a coalition will form; this uncertainty can arise fo... View full abstract»

    A simple multifaceted outranking multiple attribute decision making (MADM) method based on holistic and heuristic ideas is outlined in the paper. It makes use of preference assessment of discrete alternatives at (i) specified criteria nonconcurrently, (ii) direct expert judgments, or (iii) both. The “Dichotomy-Cut” method matches the merits of voting mechanisms with new decisive inform... View full abstract»

    The problem of calibrating a camera has been widely addressed in the past. Almost all techniques described in the literature use a known calibrating pattern and a static camera. We introduce a novel technique, based on an active camera, which does not need any predefined patterns. All that is required is a scene with some strong and stable edges. Two alternative algorithms are presented and analys... View full abstract»

    Given a belief network with evidence, the task of finding the l most probable explanations (MPE) in the belief network is that of identifying and ordering the l most probable instantiations of the nonevidence nodes. Although many approaches have been proposed for solving this problem, most work only for restricted topologies (e.g., singly connected belief networks). In this paper we will present a...

    The division of intellectual labor required to solve complex problems demands that those problems be decomposed and distributed among available “laborers.” One well-developed notion in shared problem solving is collaboration, the distribution of problem solving activities to group or system members based on their capabilities. Although collaboration enjoys wide-spread acceptance, the t... View full abstract»
