Compression and Restoration of Texture Images of Walls for 3D Visualization of Urban Buildings

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.
