Image Mosaic Based View Synthesis for Interactive Stereoscopic Display
摘要
Abstract
In stereoscopic display, view synthesis is a key technology to realize interactivity what is the ability to look around within a three dimensional (3D) scene by freely choosing a viewpoint. This paper presents an interme-diate view synthesis algorithm, combining view interpolation with view morphing based on image mosaic. Firstly,the original stereo image pairs are normalized. Then, the disparity of only object area is estimated by a predict re-eursion method to improve the matching speed and accuracy. Afterward, credible areas in left and right views should be determined and chosen to create a transitional view. At last, a method combining view interpolation and morphing is used to synthesis the intermediate view from the transitional view. Experimental results show that the edge of created intermediate view object is clear and smooth, and the processing speed of view synthesis is obvious-ly improved. This algorithm can be used in interactive stereoscopic display in various 3D video applications that an arbitrary view needs to be rendered in real-time.关键词
