Online interaction with 3D facial animation is an alternative way of face-to-face communication for distance education. 3D facial modeling is essential for virtual educational environments establishment. This article presents a novel 3D facial modeling solution that facilitates quasifacial communication for online learning. Our algorithm builds 3D facial models from a single image, with support...

Recently, image-to-image translation has been made much progress owing to the success of conditional Generative Adversarial Networks (cGANs). However, it’s still very challenging for translation tasks with the requirement of high-level visual information conversion, such as phototo-caricature translation that requires satire, exaggeration, lifelikeness and artistry. We present an approach for l...

This special issue is devoted to theoretical and empirical studies of subtle expressivity for characters and robots. People both consciously and subconsciously use subtle expressions to communicate their emotions and intentions through variations in gaze direction, voice tone and gesture speed. People also perceive changes in the internal states of others from subtle changes in such expressivit...

The ability to share the attention with another individual is essential for having intuitive interaction. Two relatively simple, but important prerequisites for this, saliency detection and attention manipulation by the robot, are identified in the first part of the paper. By creating a saliency based attentional model combined with a robot ego-sphere and by adopting attention manipulation skil...

Giorgio Vasari argued that the polyvalent term disegno in the Cinquecento should unite the arts of painting, sculpture and architecture in the Accademia del Disegno. The nature of invention, or invenzione in the united arts, was not as united; it was not the same for architecture as it was for painting. Alberti, as is well known, argued for the status of painting to be a liberal art modelled on...
