摘要
针对传统方法难以可靠估计图像中纹理单一区域像素点视差的问题,将纹理分析应用于立体匹配中,提出图像分块整体匹配的方法。首先用LBP/C纹理分析方法对图像纹理进行描述;然后进行基于区域生长的扩张检测,得到纹理单一图像块;最后对图像块进行整体匹配,得到纹理单一区域的稠密视差图。对国际标准图像进行测试,结果表明该算法能提高纹理单一区域稠密视差图的精度,具有实用价值。
Due to the difficulty of getting disparity of less textured pixels with traditional approach,block matching algorithm with texture analysis was put forward.First,the images were described by LBP/C texture analysis.Then the expansion detection based on region growing was performed,and the less textured blocks were acquired.Finally the dense disparity map of less textured area was obtained through block matching.The proposed algorithm was tested with the international standard image data and compared with som...
