Abstract

Objects and people in stereograms typically appear flat as if they were cardboard cut-outs. This is still true when the angular size of objects in the stereograms is the same as those of original scene. Howard and Rogers (1995) suggested that the phenomenon occurs because stereo pictures are viewed at a much shorter distance than the original scene. We investigated this phenomenon in relation to this scaling problem and the results showed that although it causes a significant depth reduction, the scaling from viewing distance does not fully explain the phenomenon. However, when the disparity between object and background were added, the object appeared flatter. These results suggest a new aspect for the explanation of cardboard cut-out phenomenon.
