Two approaches to incorporate approximate geometry into multi-view image coding
Two compression schemes for coding multiple images of a static scene are compared. Both codecs apply approximate 3-D scene geometry: in model-aided coding, images are predicted by model-driven disparity compensation, while the model-based coder uses the geometry to convert images into texture maps for compression. Images of real-world objects are used to evaluate both codecs. The coding performance is examined subject to varying geometry accuracy. Compression factors of up to 1000:1 at an acceptable reconstruction quality verify the usefulness of the 3-D geometry for coding multi-viewpoint imagery.
