Optical Tracking using Line Pencil Fiducials
(The Eurographics Association, 2004)
In this paper, a new pattern based optical tracking method is presented for the recognition and pose estimation of input devices for virtual or augmented reality environments. The method is based on pencils of linefiducials, ...
Feature-Based Textures
(The Eurographics Association, 2004)
This paper introduces feature-based textures, a new image representation that combines features and samples for high-quality texture mapping. Features identify boundaries within an image where samples change discontinuously. ...
A New Fingerprint Image Segmentation Algorithm Based on ROIO
(The Eurographics Association, 2004)
We present a new fast and effective method of fingerprint image segmentation, which is different from traditio-nal methods that usually use some certain features to segment diversified images. Based on the region of ...
Memory-Savvy Distributed Interactive Ray Tracing
(The Eurographics Association, 2004)
Interactive ray tracing in a cluster environment requires paying close attention to the constraints of a loosely coupled distributed system. To render large scenes interactively, memory limits and network latency must be ...
Simultaneous Tracking of Multiple Objects for Augmented Reality Applications
(The Eurographics Association, 2004)
This paper presents an appearance-based image processing and tracking algorithm which is applied in a distributed Augmented Reality (AR) system. The tracker is computer vision based and is capable of simultaneous tracking ...
Programmable Style for NPR Line Drawing
(The Eurographics Association, 2004)
This paper introduces a programmable approach to non-photorealistic line drawing from 3D models, inspired by programmable shaders in traditional rendering. We propose a new image creation model where all operations are ...
Smooth Reconstruction and Compact Representation of Reflectance Functions for Image-based Relighting
(The Eurographics Association, 2004)
In this paper we present a new method to reconstruct reflectance functions for image-based relighting. A reflectance function describes how a pixel in a photograph is observed depending on the incident illumination on the ...
Light Space Perspective Shadow Maps
(The Eurographics Association, 2004)
In this paper, we present a new shadow mapping technique that improves upon the quality of perspective and uniform shadow maps. Our technique uses a perspective transform specified in light space which allows treating all ...
Rendering Evolution at Industrial Light and Magic
(The Eurographics Association, 2004)
From Jurassic Park to Van Helsing, the rendering technologies at ILM have evolved over the last 10 years, both to satisfy the high demands of our clients and also those of the general public. State-of-the-art rendering ...
A Cameraphone-Based Approach for the Generation of 3D Models from Paper Sketches .
(The Eurographics Association, 2004)
Due to the advantages it offers, a sketch-based user-interface (UI) has been utilised in various domains, such as 3D modelling, 'graphical user-interface' design, 3D animation of cartoon characters, etc. However, its ...
