This paper presents a Multi-valued Decision Diagram (MDD) that has additional null-value and all-value edges. The MDD is based on a multivalued algebra that augments multi-valued variables to allow a null output value. A null output value represents the lack of any valid value for a given input combination (akin to an output don’t care, but its value cannot be changed). A side effect of the nul...

Facial expression is one of the most expressive ways for human beings to deliver their emotion, intention, and other nonverbal messages in face to face communications. In this chapter, a layered parametric framework is proposed to synthesize the emotional facial expressions for an MPEG4 compliant talking avatar based on the three dimensional PAD model, including pleasure-displeasure, arousal-no...

In this contribution we investigate how to describe the results and usage of evolutionary synthesis models. In particular, we look for an explicit and quantitative description of the parameter space of synthesis models and the evaluation of their associated uncertainties and dispersion. First, we need to understand what synthesis models actually compute: we show that a synthetic stellar populat...

Because domino logic design offers smaller area and higher speed than conventional CMOS design, it is very popular in the high performance processor design. However, domino logic suffers from several design problems and one of the most notable design problems is the charge sharing problem. In domino logic, there are two operations: the pre-charge phase and the evaluation phase. The charge shari...

In this paper, we propose parameter generation methods using rich context models in HMM-based speech synthesis as yet another hybrid method combining HMM-based speech synthesis and unit selection synthesis. In the traditional HMM-based speech synthesis, generated speech parameters tend to be excessively smoothed and they cause muffled sounds in synthetic speech. To alleviate this problem, sever...

The integration of text-to-speech (TTS) synthesis and animation of synthetic faces allows new applications like visual human computer interfaces using agents or avatars. The TTS informs the talking head when phonemes are spoken. The appropriate mouth shapes are animated and rendered while the TTS produces the sound. We call this integrated system of TTS and animation a Visual TTS (VTTS). This p...

Texture synthesis algorithms have been researched extensively in the past decade. However, most synthesis algorithms are governed by a set of parameters and produce different results depending on which parameter settings are chosen in conjunction with an exemplar used as a basis for synthesis. So far, automatically selecting parameters suitable for synthesis has been a relatively unexplored top...

In this paper we present a novel speaker-dependent speech synthesis algorithm based on modeling temporal trajecto-ries of the speech Line Spectrum Pair Frequencies (LSFs). The overall approach is integrated into a pitch-synchronous analysis/synthesis framework and is shown to allow the synthesis of speaker-dependent voice characteristics through an automatic parameter learning algorithm.

In this paper we present PRISM-PSY, a novel tool that performs precise GPU-accelerated parameter synthesis for continuous-time Markov chains and time-bounded temporal logic specifications. We redesign, in terms of matrix-vector operations, the recently formulated algorithms for precise parameter synthesis in order to enable effective dataparallel processing, which results in significant acceler...
