Methods that use the underlying (influencing, contributing, performance-shaping, etc.) factors in human operator error analysis, in general, inadequately incorporate them into the operator's model of erroneous action. This paper describes the method of error analysis in which the factors of the operator's performance and the underlying factors are considered to be coherent on all stages of the erroneous...
Human immune system has been an inspiration for the fields of computer science, engineering and medicine. Over the last few years, there has been an ever increasing development in the area of artificial immune systems. Risk of falling is one of the most important risks in medicine and quality patient care. Patient classification criteria for the risk of falling are measured by the Morse scale. This...
A perception-aware motion-compensated frame interpolation algorithm has been proposed. There is no motion estimation process in this low cost frame rate up-conversion (FRUC) algorithm. With the proposed filter-based MV processing techniques and the motion compensation (MC) decision in a motion compensated interpolation (MCI) stage, the proposed algorithm reduces the memory and bandwidth requirement...
Automated systems are increasingly complex, making it hard to design interfaces for human operators. Human-machine interaction (HMI) errors like automation surprises are more likely to appear and lead to system failures or accidents. In previous work, we studied the problem of generating system abstractions, called mental models, that facilitate system understanding while allowing proper control of...
The growth of wireless devices with short-range communications capabilities is making research into Pocket Switched Networks (PSN)s more appealing. While some recent research has investigated the role of location in predicting the mobility patterns of autonomous agents within PSNs, little attention has been paid to the location as a resource itself. In this paper we investigate the potential for stationary...
Due to the sheer volume of text generated by a micro log site like Twitter, it is often difficult to fully understand what is being said about various topics. In an attempt to understand micro logs better, this paper compares algorithms for extractive summarization of micro log posts. We present two algorithms that produce summaries by selecting several posts from a given set. We evaluate the generated...
Using handwriting as a form of communication with personal devices has recently attained notable popularity owing to the increasing use of touchscreen devices and the tendency to make human-computer interaction more natural. However, as current handwritten character recognition algorithms implement high resource-consuming operations, their use is limited to the development of complex and specific...
Emotion classification and retrieval in video is important in video analysis. It has great significance for the classification of video management and video retrieval. In this paper, we design an emotion classification and retrieval system for video based on user experience. We analyzed problems of the current emotion classification and retrieval algorithm. First we define the type of video classified...
Open problems are defined differently in document image analysis than in the physical sciences, theoretical computer science, or mathematics. Instead of a formal definition, problems in DIA are stated in terms of automation of an application area (e.g., postal address reading) or a scientific sub field (e.g., image compression). The notion of a successful solution may be based on (1) the relative...
This paper proposes an operation management system to analyze operating workflows as preliminary step for the continual improvement of them. To provide highly dependable and cost effective services, telecom operators must decrease human errors and operational costs. It is common for the operators to conduct operating procedures by following predefined operational workflows. However, it is difficult...
When visualizing graphs into node-link diagrams, angular resolution is often used as one of the aesthetic criteria measuring the diagram quality in terms of human comprehension. However, angular resolution has not been empirically validated for its relevance to humans. In addition, although many force-directed algorithms have been proposed for automatic graph drawing, performance evaluation of these...
Texture analysis is viewed as a method to enhance the diagnosis power of classical B-mode ultrasound image. Present study aims to evaluate the dependence between the human expert and the performance of such a texture analysis system in predicting the cirrhosis in chronic hepatitis C patients. 125 consecutive chronic hepatitis C patients were included in this study. All the patients had positive HCV-RNA...
Establishes the knowledge complex mode of design rules of civil avionics SVS (Synthetic Vision Systems) aiming at its peculiarity of operation and being based on the experienced data being evaluated by the resourceful pilots, and mines the correlative relationship between disfigurements from the contents of EFIS display and the human errors of itself being based on rough set in order to obtain the...
Study the global histogram algorithm and the rigid block algorithm in image retrieval, in order to improve the lack of spatial information in the global histogram, and to improve the lack of rotation invariance and image integrity in the rigid block, this paper proposed block weighting — the color feature algorithm. The algorithm first conduct color image a rigid segmentation, then sort the second...
In real-time video transmission, the loss of packet results in visual quality degraded for the succeeding frames. This paper proposes an efficient full frame algorithm for depth-based 3-D videos. Each frame can be regarded as combination of objects. True motion estimation (TME) and depth map are exploited to calculate the motion vector (MV) for each object. In this paper, the object is defined as...
In this paper we introduce the design and implementation of an automatic camera servo system using improved frame differential algorithm which can be used in varying environments. The system uses frame differential algorithm which is improved by us to analyse the screen shots. In order to make sure that the moving object is always in the center of the shot, the system detects the target motion and...
In this paper, we present a complete and novel workflow for quantitative nuclear feature analysis of glioblas-toma using high-throughput whole-slide microscopy image processing as it relates to treatment response and patient survival. With a complete suite of computer algorithms, large numbers of micro-anatomical structures, in this case nuclei, are analyzed and represented efficiently from whole-slide...
Automated tracing tools employ information retrieval (IR) methods to recover traceability links between software artifacts. A large body of research is available on the back-end design of such tools, including artifacts indexing and the underlying IR mechanism. In contrast, less attention has been paid to the front-end presentation of the retrieved results. This paper describes TraCter, a result categorization...
A brief discussion of PSO from 1995 to the development process, analysis of the particle swarm algorithm improvement strategy, the paper used by introducing a phase-out factor, proposed a new particle swarm out strategy, forming a WPSO law, and with the traditional PSO was compared using the optimization function experiments to compare the results show that, WPSO value in the optimization better than...
Bow action usually expresses human respect intention. The process of human bow is companied with fuzziness and randomness. Current control methods for virtual human's bow cannot describe the uncertainties. A cloud model based method is proposed to control virtual human's bow action. The method can describe the two uncertainties in the process of bow indicating respect intention. Clouds of maximal...
