A paintbrush-like image transformation is proposed in this paper. It is based on a random searching to insert brush-strokes into a generated image at decreasing scale of brush-sizes, without predefined models or interaction. One of the goals of the method is to transform the image into a representation that is very similar to the human sensation of artistic images. We introduce a sequential mul...

This paper looks at a method of blending different artistic filters together to create a range of artistic effects. Instead of using a single painterly rendering technique, the methods used in three different filters can be blended together in a user defined way. The filters are arranged in a triangular structure where the user defines their chosen painting style by choosing a point in the tria...

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....

Artistic style transfer is an image synthesis problem where the content of an image is reproduced with the style of another. Recent works show that a visually appealing style transfer can be achieved by using the hidden activations of a pretrained convolutional neural network. However, existing methods either apply (i) an optimization procedure that works for any style image but is very expensi...

In this thesis, we present a semi-automatic method for the generation of bas-reliefs from a given shape. A Bas-reliefs is an artistic sculptural representation of a three dimensional scene which possesses a negligible depth. The main idea behind our method is to work with a range image, whose depth interval size is compressed in a feature preserving way. Our approach operates in the gradient do...

The National Oceanic and Atmospheric Administration (NOAA) National Hurricane Center’s (NHC) Tropical Cyclone Advisories contain several heterogeneous data types that are difficult to represent graphically in a single image. However, the understanding of these statements is vital for human safety in areas that are regularly affected by these devastating storms. Thus, the motivation behind the c...

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,...

We present a novel framework for non-photorealistic rendering (NPR) based on view-dependent geometric simplification techniques. Following a common thread in NPR research, we represent the model as a system of particles, which will be rendered as strokes in the final image and which may optionally overlay a polygonal surface. Our primary contribution is the use of a hierarchical view-dependent ...
