Paper: ACM SCA (2002): “Controlled animation of video sprites”

Citation [bibtex key= 2002-Schodl-CAVS] Abstract We introduce a new optimization algorithm for video sprites to animate realistic-looking characters. Video sprites are animations created by rearranging recorded video frames of a moving object. Our new technique to find good frame arrangements is based on repeated partial replacements of the sequence. It allows the user to specify […]

Paper in CVPR 2001: "Depth Layers from Occlusions"

Depth Layers from Occlusions [bibtex file=IrfanEssaWS.bib key=2001-Schodl-DLFO] Abstract We present a method to extract relative depth information from an uncalibrated monocular video sequence. Our method detects occlusions caused by an object moving in a static scene to infer relative depth relationships between scene parts. Our approach does not rely on any strong assumptions about the […]

Paper: ACM SIGGRAPH (2000) "Video textures"

Paper [bibtex file=IrfanEssaWS.bib key=2000-Schodl-VT] Abstract This paper introduces a new type of medium, called a video texture, which has qualities somewhere between those of a photograph and a video. A video texture provides a continuous infinitely varying stream of images. While the individual frames of a video texture may be repeated from time to time, […]
