This paper discusses a new method for capturing the complete appearanceof both synthetic and realworld objects and scenes, representing this information, and then using this representation to render images of the object from new camera positions. Unlike the shape capture process traditionally used in computer vision and the rendering process traditionally used in computer graphics, our approach does not rely on geometric representations. Instead we sample and reconstruct a 4D function, which we call a Lumigraph. The Lumigraph is a subsetof the complete plenoptic function that describes the flow of light at all positions in all directions. With the Lumigraph, newimages of the object can be generated very quickly, independent of the geometric or illumination complexity of the scene or object. The paper discusses a complete working system including the capture of samples, the construction of the Lumigraph, and the subsequent rendering of images from this new representation.

提出一种在图像分割基础上生成稠密视差图的立体匹配算法，利用滑动窗口生成鲁棒性较好的视差空间图DSI，运用分水岭算法将图像分割成多个小区域，根据每个区域在视差空间图内的视差分布情况计算该区域的信赖度，并综合各区域的邻域对其产生的影响，以获得稠密视差图，采用国际标准数据对该算法进行测试，实验结果表明，该算法能够获得较好的匹配结果

针对Tao的平滑表面假设提出了一种基于图像分割的快速立体匹配算法。算法把参考图分割成多个区域，计算其中可靠区域的平面模板，通过贪婪算法把平面模板分配给不可靠区域使得全局评价函数取到最小值。该算法能克服基于局部算法中存在的边界模糊，以及低纹理区误匹配严重的缺点，解决了传统的基于全局算法中计算量过大的问题。实验表明，该算法能同时满足高精度和高实时性的要求。
