基于互信息的建筑物立面影像重复纹理检测方法

Mutual Information Based Building Facade Texture Image Repetitive Texture Detection

建筑物影像在用于建筑物三维建模的过程中,常常由于树木、行人的遮挡而受到影响,但建筑物一般包含门、窗等重复排列信息,对这些信息的提取将有助于无遮挡建筑物立面纹理的生成。以互信息作为匹配测度,检测建筑物上的重复纹理,实现建筑物上的重复结构剔除,得到不含重复纹理的建筑物立面影像。

Building fa9 ade image is often used in building 3 D modelling,but it is always affected by occlusion such as trees and pedestrians.So it is very important to produce occlusion-free building fa9 ade texture.AS most buildings contain windows,doors,which generally satisfies some arrangement regulations（repetition or symmetry）.Extracting the repetitive information will be helpful to the production of the occlusion-free fa9 ade texture.This paper uses mutual information as registration measurement to detect repetitive texture in building fa9 ade texture image,remove duplicate structures on buildings,and obtain the facade images with no repetitive texture.
