| 摘 要： | 以城市三维可视化中的房屋墙面纹理图像为对象，就其压缩与恢复的方法进行了研究，提出了一种基于自相似性墙面纹理分割的纹理图像压缩与恢复方法，以及对由于遮挡而墙面不完整的纹理图像的复原方法，并通过实例说明了此种方法对于城市三维可视墙面纹理贴图的实用性。

| Abstract: | A method for texture image's compression and restoration is put forward. This method is based on the texture segmentation. The segmentation units are used as the compressing and restoring object. This method can not only realize the image compression, but also get rid of the interferences and then reconstruct the clean profile texture of buildings. The method takes advantage of higher compression ratio than other conventional compression methods, and the algorithm is fast enough to satisfy the 3D reconstruction. This method can fully satisfy the 3D visualization of urban landscape and is more suitable for the profile texture image compression of 3D visualization than other traditional compression methods. |
