In games we frequently see large gatherings of crowds of characters; for example, an army or a rowdy crowd in a stadium. These crowds may seem realistic from a far away view, however, up close this impression fails as the viewer approaches the characters and the illusion of detailed creatures rapidly breaks down. We describe a method for managing level of detail and maintaining high quality ren...

This paper presents a voice source analysis method by studying the spectral characters of LF model and their representation in output speech signal. The estimation of source features is defined as the set of LF parameter whose spectrum has the most similar characters in frequency domain, including glottal formant and spectral tilt, with the corresponding characters held by the STRAIGHT spectrum...

The structure of Chinese characters is reviewed and seen to be best represented as a 3-layer hierarchy of character, radical and stroke. Fuzzy possibilistic reasoning is then put forward as an appropriate set of conceptual tools to investigate the automatic recognition of these characters. Associative memory artificial neural network algorithms form a suitable technique for realising these conc...

Physics simulation offers the possibility of truly responsive and realistic animation. Despite wide adoption of physics simulation for the animation of passive phenomena, such as rigid objects, fluids, cloths and rag-doll characters, commercial applications still resort to kinematics-based approaches for the animation of actively controlled characters. However, in recent years, research on inte...

With the increase in realism of games based in stadiums and urban environments, real-time crowds are becoming essential in order to provide a believable environment. However, realism is still largely lacking due to the computation required. In this paper, we describe the pipeline of work needed in order to prepare and export models from a 3D modelling package into a crowd system. For our crowd,...

The interactive approach of character animation requires sophisticated motion synthesis algorithms to generate poses and motions for unpredictable events. Traditional animation techniques used alone cannot produce the needed degree of realism or the degree of controllability required for virtual characters. Motion-capture techniques and the physical simulation of characters, when combined, offe...

Let E be an elliptic curve over Q with complex multiplication by the ring of integers of an imaginary quadratic eld. Let be the Hecke character associated to E by the theory of complex multiplication. Let be the complex conjugate character of. For a pair of integers k and j, deene the Hecke character ' = '(k; j) = k j. Let p be a prime where E has good, ordinary reduction. Let p be a xed prime ...
