This paper describes our methods for repairing and restoring images of hidden paintings (paintings that have been painted over and are now covered by a new surface painting) that have been obtained via noninvasive X-ray fluorescence imaging of their canvases. This recently developed imaging technique measures the concentrations of various chemical elements at each two-dimensional spatial locati...

The relationship between the activity of painting and performance of stereotyped and other stress-related behaviour was investigated in four captive Asian elephants at Melbourne Zoo, Australia. The activity involved the elephant being instructed to paint on a canvas by its keeper in front of an audience. Painting by elephants in zoos is commonly believed to be a form of enrichment, but this ass...

This paper presents a novel interactive system for guiding artists to paint using traditional media and tools. The enabling technology is a multi-projector display capable of controlling the appearance of an artist’s canvas. Artists are guided by this display-on-canvas to execute painting techniques. The artist paints according to a linear process of painting by numbers, one layer at a time. Ea...

This paper presents a novel Chinese calligraphy and painting system, which serves as an expressive vehicle for interactively creating Chinese traditional calligraphy and ink-wash painting works. We developed a brush model which gives the user natural control of complex brush strokes. This model enhances the realistic sense of the user’s manipulating the pen with the pressure sense. We also deve...

In this article he develops his proposal further and shows that shapes act as syntactic elements in the languages of painting styles. He meets Nelson Goodman's objections to his proposal by showing that shapes meet the criterion of syntactic discreteness proposed by the latter to separate linguistic from other sy...
