摘要: 针对基于图像三维重构得到的三维形状的纹理映射算法通常存在接缝现象的问题,提出一种无接缝纹理映射算法。该算法通过建立三维网格顶点和视点之间的马尔可夫随机场模型,利用重心坐标权重插值进行颜色填充,构造出一个无接缝的纹理图像。实验结果表明,马尔可夫随机场模型可以在保证纹理图像质量的同时最小化接缝现象,在此基础上的权重颜色插值方法能够完全消除接缝现象。

Abstract: A seamless texture mapping algorithm is proposed since that in the image-based modeling context, color discontinuities at patch boundaries is a crucial issue due to photometric and geometric inaccuracies. With Markov random field which relates the mesh vertices to the viewpoints, a seamless texture map is constructed via barycentric coordinate weight color interpolation. Experimental results show that the Markov random field energy model can ensure texture map visual quality while minimizes the seam, and the seam can be totally removed with the help of the weight color interpolation.

Key words: realistic modeling, texture mapping, Markov random field, seam elimination
