BACKGROUND Two professional painters experienced significant changes in their art as the main consequence of minor stroke located in the left occipital lobe or thalamus. METHODS The features of this artistic conversion were analysed on the basis of extensive neurological, neuropsychological, and psychiatric evaluations. RESULTS Both painters, initially unaware of the artistic changes, exhib...

A technique is presented for line art rendering of scenes composed of freeform surfaces. The line art that is created for parametric surfaces is practically intrinsic and is globally invariant to changes in the surface parameterization. This method is equally applicable for line art rendering of implicit forms, creating a unified line art rendering method for both parametric and implicit forms....

The application of multimedia technology has realized the transformation people’s production and lifestyle, also promoted improvement aesthetic ability. At present, in field art is increasing, traditional artistic expression been unable to satisfy appreciation beauty. Using high-efficiency extensive communication technology, this paper aims study research on expressions visual design environmen...

Collages have been a common form of artistic expression since their first appearance in China around 200 BC. Recently, with the advance of digital cameras and digital image editing tools, collages have gained popularity also as a summarization tool. This paper proposes an approach for automating collage construction, which is based on assembling regions of interest of arbitrary shape in a puzzl...

In recent years, several techniques have been proposed for automatically producing line-art illustrations. In this paper a new non photo-realistic rendering scheme for triangulated surfaces is presented. In contrast to prior approaches with parametric surfaces, there is no global parameterization for triangle meshes. So a new approach is made to automatically generate a direction field for the ...

An artistic rendering method of free-form surfaces with the aid of half-toned text that is laid-out on the given surface is presented. The layout of the text is computed using symbolic composition of the free-form parametric surface S(u, v) with cubic or linear Bézier curve segments C(t) = {cu(t), cv(t)}, comprising the outline of the text symbols. Once the layout is constructed on the surface,...
