Composition of novel views through an efficient image warping

This paper presents an efficient inverse warping algorithm for generating novel views from multiple reference images taken from different viewpoints. The method proceeds in three steps: preprocess for edge-pixel extraction, inverse warping from the primary image, and hole filling from remaining reference images. In using advantages of epipolar-line features and the depth discontinuity in the reference images, the inverse warping can be efficiently applied in segments, accelerating the rendering process substantially. Two acceleration techniques are proposed at the last stage for hole filling. By using the algorithm proposed, we may navigate a virtual environment at an interactive rate.
