Automatic non-photorealistic rendering through soft-shading removal: a colour-vision approach

نویسنده

  • A. Olmos
چکیده

This paper presents a non-photorealistic rendering algorithm that produces "stylised-style" images by removing the soft shading from the image and by giving objects extra definition through black outlines. The method of shading removal is based on a model of the architecture of the human colour vision system. Some image results are provided and the possible extension of the algorithm using a back-propagation neural network is discussed.

A Hybrid Approach to Real-Time Abstraction

To faithfully represent a scene through non-photorealistic rendering (NPR), it is vital that all available scene data be taken into account. We present an automatic hybrid framework for creating abstractions of 3D scenes in real-time. Our approach uses a combination of object-space and image-space information to produce stylistic and reliable results. Calculations using scene vertex data are co...

Interactive Volume Illustration

In this paper we describe non-photorealistic rendering techniques for volumetric data sets. First, we outline an automatic approach that generates line drawings to illustrate such data sets and to augment traditional volume rendering techniques. For a number of seed points that are placed appropriately to represent selected volume structures curvature lines are traced and encoded by a sparse se...

Use of non-photorealistic rendering and photometric stereo in making bas-reliefs from photographs

Automatic bas-relief generation from 2D photographs potentially has applications to coinage, commemorative medals and souvenirs. However current methods are not yet ready for real use in industry due to insufficient artistic effect, noticeable distortion, and unbalanced contrast. We previously proposed a shape-from-shading (SFS) based method to automatically generate bas-reliefs from single fro...

Introduction to 3D Non-Photorealistic Rendering: Silhouettes and Outlines

In these notes, we survey some of the basic tools used for non-photorealistic rendering of 3D scenes. We will primarily focus on detecting outlines of object shape: silhouettes, boundaries, and creases. (Hatching and shading, which are also very important for communicating shape, are discussed elsewhere in the course notes.) The algorithms in this section can be divided into algorithms that ope...

Artistic minimal rendering with lines and blocks

Many non-photorealistic rendering techniques exist to produce artistic effects from given images. Inspired by various artists, interesting effects can be produced by using a minimal rendering, where the minimum refers to the number of tones as well as the number and complexity of the primitives used for rendering. Our method is based on various computer vision techniques, and uses a combination...
