Abstract: This paper proposes a feasible change detection method of constructions by use of region feature. It studies the formation of determinant function for region changes, generalization of region characteristics, joint change determinants of multi-factor for regions, minimization of the influence by pixel value variance due to different acquisition time. The method can not only weaken the false change through pixel value variance, but also suit for detecting changes of varying region sizes.

摘要： 提出了一种基于图像区域特征的人工目标变化检测方法，在研究解决区域特征变化准则函数构造、特征量标准化处理、多特征联合变化判定规则确定等问题的基础上，能够抑制单纯由像素灰度差异引起的伪变化，而且对不同尺寸的区域变化有较好的适应性。
