IEEE/ASME (AIM) International Conference on Advanced Intelligent Mechatronics

作者： Woongsoon Kim Seungkeol Choe Sangwon Kim Chulwoong Lee Computer Graphics Laboratory Systems Engineering Research Institute Taejon South Korea

Summary form only given. Speech synthesis plays an important role in Korean speech animation since it produces the sequence of phonetic phonemes by processing nearly all of the elements like phonological rules, to enunciate the input text. To make a speaking facial model which uses the motions of lips and surrounding part of the face, it is necessary to extract visual informations from the output of a speech synthesis system. The paper investigates a set of facial elements enough to make a realistic speech animation by examining the visual factors not available from speech synthesis systems as well as extracting signals from the result of speech synthesis that will cause visible changes in facial expression.

Classification and extension of universal human emotions

Classification and extension of universal human emotions

Summary form only given. For a long time, the fundamental six emotions proposed by Ekman were widely used for the expression of universal human emotions. But the classification can not present the facial expression directly from the uprising conceptual emotion. We notice that this problem is caused by the conceptuality of the emotions which can have a lot of expressions on a facial model. We present a new standard to classify the emotions in the expression sense, not in the conceptuality. This means we recognize each facial expressions as a meaningful visual unit. Each meaning of emotional expressions help us to define a visual level of detail of the expressions. Moreover the methodology which leads to the concept of expression can be applied to non-emotional expressions. We define additional facial expression from the expressions proposed by Faigin which express human physical state. The birth of the standard to express facial actions enable us both to classify emotional expression and to investigate each expression in detail, as well as to extend the region of facial expressions.

As a popular evolutionary algorithm, artificial bee colony (ABC) algorithm has been successfully applied into the threshold-based image segmentation problem. Based on our analysis, we find that the Otsu segmentation function is separable which means each variable is independent. Due to its one-dimensional search strategy and relative power global but poorer local search abilities, ABC could find an acceptable but not precise segmentation results. For making more precise search and further enhancing the achievements on image segmentation, we propose an Otsu segmentation method based on a new ABC algorithm with an improved scout bee strategy. Different from the traditional scout bee strategy, we use a local search strategy when a bee stagnates for a defined value. The experimental results on Berkeley segmentation database demonstrate the effectiveness of our algorithm. © 2020, Springer Science and Business Media Deutschland GmbH. All rights reserved.

In this paper we consider implementing optical burst switching as a technology for building Grids with computationally intensive requirements. This architecture has been referred to as Grid-over-OBS (GoOBS). First, we briefly describe the proposed layered Grid architecture and show how OBS can be positioned within the Grid architecture. Then, we present a generic framework for anycast routing in the context of GoOBS when requests don't have an explicit destination address and they can be serviced by any appropriate Grid resource. We also develop several algorithms to support anycasting when only a single copy of a request is transmitted. Through simulation analysis, we show the performance of our anycast algorithms and compare them with traditional shortest-path unicast routing in which all jobs have specific addresses. Our performance analysis focuses on blocking probability of requests and average end-to-end delay. © 2006 IEEE.

One of the major problems in developing computeraided design software is the establishment of effective man-machine communication. This paper describes a computer-aided plate girder design software package and its man-machine interface using natural language processing techniques. The natural language interpreter takes advantage of the user's communication and technical skills and accepts commands in the user's native language. The user can verify the correct interpretation of the commands from the responsive graphic display of the design. © 1986 Springer-Verlag New York Inc.

Simulation accuracy of a methodology for composable modeling of microelectromechanical systems (MEMS) is assessed by comparing against analytic equations and finite element simulations. Several MEMS canonical problems are composed hierarchically as networks of simple elements with models written in an analog hardware description language. Schematics built from this model library, called NODAS (nodal design of actuators and sensors), produce DC simulation results that are accurate to at least three digits, demonstrating suitable accuracy and lumping trade-offs. © 2003 IEEE.

Surface Reconstruction of Freeform Objects Based on Multiresolution Volumetric Method

Recently developed 3D scanning devices are capable of capturing point clouds, as well as additional information, such as normals and texture. This paper describes a new and fast reverse engineering method for creating a 3D computerized model from data captured by such contemporary 3D scanning devices. The proposed method aggregates large-scale 3D scanned data into an extended Hierarchical Space Decomposition Model (HSDM) based on Octree data structure. This model can represent both an object’s boundary surface and its interior volume. The HSDM enables data reduction, while preserving sharp geometrical features and object topology. As a result the execution time of the reconstruction process is significantly reduced. Moreover, the proposed model naturally allows multiresolution surface reconstruction, represented by a mesh with regular properties. Based on the proposed volumetric model, the surface reconstruction process becomes more robust and stable with respect to sampling noise.

Animation of human walking in virtual environments

computer Animation

作者： Shih-Kai Chung J.K. Hahn Institute for Computer Graphics School of Engineering and Applied Science George Washington University USA

This paper presents an interactive hierarchical motion control system dedicated to the animation of human figure locomotion in virtual environments. As observed in gait experiments, controlling the trajectories of the feet during gait is a precise end-point control task. Inverse kinematics with optimal approaches are used to control the complex relationships between the motion of the body and the coordination of its legs. For each step, the simulation of the support leg is executed first, followed by the swing leg, which incorporates the position of the pelvis from the support leg. That is, the foot placement of the support leg serves as the kinematics constraint while the position of the pelvis is defined through the evaluation of a control criteria optimization. Then, the swing leg movement is defined to satisfy two criteria in order: collision avoidance and control criteria optimization. Finally, animation attributes, such as controlling parameters and pre-processed motion modules, are applied to achieve a variety of personalities and walking styles.
