Nonlinear image warping or image resampling is a necessary step in many current and upcoming video applications, such as video retargeting, stereoscopic 3-D mapping, and multiview synthesis.

We introduce a single unifying framework for a wide range of content-aware image warping tasks using a finite element method (FEM).

We investigate new methods for compositing live action stereo 3D, given two stereo camera systems and a corresponding depth map.

Current trends in video technology indicate a significant increase in spatial and temporal resolution of video data. Recently, a linear-runtime feature diffusion algorithm was presented which aims for fast and accurate processing of such high-resolution data.

In this paper, a method for efficient warp coding is presented. Coded warps are transmitted together with stereo or multi-view video to enable additional functionalities at the receiver-side through image-domain-warping, e.g. depth adaption for stereo displays or support of multi-view autostereoscopic Displays.

This paper provides details on a complete integration of Content adaptive Spatial Scalability (CASS) into the scalable video coding extension of H.264/AVC (SVC).

In this paper, a video rendering ASIC for multiview automultiscopic displays using an image domain warping approach is presented.

We present an evaluation of different resampling strategies for autostereoscopic multiview displays. In particular, we compare the computational efficiency, memory requirements, and image quality of different resampling algorithms with focus on real-time architectures.

This paper addresses the problem of unintended light contributions due to physical properties of display systems. An example of such unintended contribution is crosstalk in stereoscopic 3D display systems, often referred to as ghosting.

We present a method that brings the benefits of physics-based simulations to traditional animation pipelines. We formulate the equations of motions in the subspace of deformations defined by an animator’s rig.
