Light and Color as Visual Expressive Means of Modern Documentaries

VRML as means of expressive 4D illustration in CAM education

Computer graphics (CGr) lies in the fundaments of computer aided engineering (CAE). As a result from the fast development in both CGr and CAE, more and more computer aided systems (CA-systems) have been ported on low-end and personal computers. Despite the continuous drop in the CA-system prices, this type of software is still very expensive compared to typical office applications. This paper d...

Assisted Visual Servoing by Means of Structured Light

Expressive audio-visual speech

We aim at the realization of an Embodied Conversational Agent able to interact naturally and emotionally with user. In particular, the agent should behave expressively. Specifying for a given emotion, its corresponding facial expression will not produce the sensation of expressivity. To do so, one needs to specify parameters such as intensity, tension, movement property. Moreover, emotion affec...

Predicting Cut Rose Stages of Development and Leaf Color Variations by Means of Image Analysis Technique

The monitor and prediction of crop developmental stages, particularly harvest time, play an important role in planning greenhouse cropping programs and timetables by cut rose producers. There have been many scientific reports on the application of image analysis technology in estimating greenhouse crop growth stages. In the present research, we studied leaf color variations over time by taking ...

Visual inferences of material changes: color as clue and distraction.

In a snapshot, a scene consists of things, but across time, the world consists of processes. Some are cyclical, for example, trees changing foliage through the seasons, surfaces getting wet and drying out; others are unidirectional, for example, fruit ripening and then decaying, or dust accumulating on surfaces. Chemical and physical properties of objects provide them with specific surface patt...
