Efficient displacement Mapping by Image Warping

Abstract. While displacement maps can provide a rich set of visual detail on otherwise simple surfaces they have always been very expensive to render. Rendering has only been done using ray tracing or by introducing a great number of micro-polygons. We present a new image-based approach by showing that rendering displacement maps is sufficiently similar to image warping and introduce a new warp...

The Integrating Resampler and Efficient Image Warping

This paper introduces integrating resamplers as an efficient method for image warping using a class of imaging-consistent reconstruction/restoration algorithms proposed in [Boult and Wolberg-1993]. Examples are given to show the use of the integrating resamplers described herein for two low-level computer vision applications. The first is geometric correction for images degraded by radial lens ...

Efficient 3D Image Warping for Composing Novel Views

This paper presents an efficient inverse warping algorithm for generating novel views by combining multiple reference images taken from different viewpoints. The method proceeds in three steps. Firstly, the reference images are preprocessed for extracling edge pixels. Secondly, an inverse warping is performed to render the desired image from one primary reference image. By taking advantages of ...

Efficient Reconstruction Techniques for Post-Rendering 3D Image Warping

Image-based rendering replaces the difficult physical simulation problem of conventional computer graphics with a difficult reconstruction problem. In this paper, we introduce efficient methods for eliminating common reconstruction artifacts in 3D image warping. These methods are suitable for hardware implementation. We study the reconstruction problem in the context of the 3D warp’s applicatio...
