Perceptually Realistic Flower Generation

Perceptually Realistic Behavior through Alibi Generation

Real-time pedestrian simulation for open-world games involves aggressive behavior simplification and culling to keep computational cost under control, but it is diffficult to predict whether these techniques will become unrealistic in certain situations. We propose a method of perceptually simulating highly realistic pedestrian behavior in virtual cities in realtime. Designers build a highly re...

Constructing Physically Realistic VCV Stimuli for the Perception of Stop Voicing in European Portuguese

In this book chapter we present the generation of physically realistic stimuli with a biomechanical speech production model, with the aim to produce perceptually appropriate VCV sets for the European Portuguese (EP) voicing distinction. The duration measures necessary for the biomechanical model were extracted from an extensive EP speech production database, recorded for this aim. The same data...

Indexing flowers by color names using domain knowledge-driven segmentation

We describe a solution to the problem of indexing images of flowers for searching a flower patents database by color. We use a natural language color classification derived from the ISCC-NBS color system and the X Window color names to effectively use the domain knowledge available, provide perceptually correct retrieval and allow natural language queries. We have developed an automatic iterati...

Realistic Virtual Reality and Perception

John Dilworth [Philosophical Psychology 23(2010), pp. 23-42] Realistic uses of Virtual Reality (VR) technology closely integrate user training on virtual objects with VR-assisted user interactions with real objects. This paper shows how the Interactive Theory of Perception (ITP) may be extended to cover such cases. Virtual objects are explained as concrete models (CMs) that have an inner genera...
