摘要:

阴影是遥感影像的解译标志之一,然而在高分辨率遥感影像变化检测中,阴影所产生的“伪变化”是导致错检的主要原因之一。为此,提出了一种结合阴影补偿与多尺度融合的对象级高分遥感影像变化检测方法。在面向对象的变化检测框架下,首先提取遥感影像中的地物阴影,然后对多尺度变化检测进行阴影补偿。其中,通过构建一种尺度间互信息最小化的目标函数实现了尺度参数的自适应提取。在此基础上,结合所提出的阴影补偿因子,设计了一种基于D-S证据理论的决策级多尺度融合策略,并进一步对变化强度等级进行了划分。实验证明,该方法能够较好地解决阴影所导致的错检问题,显著提高变化检测精度。

Abstract:

As an interpreting symbol of remote sensing images,shadow,however,brings about “pseudo changes”,which is one of the main sources leading to error detection in high-resolution remote sensing image change detection.For this issue,an object-based high-resolution remote sensing image change detection method was proposed combining with shadow compensation and multi-scale fusion.In the object orientation detection framework,the shadows in the remote sensing images were extracted.Then multi-scale change detection was conducted with shadow compensation.In the process,an objective function was constructed of mutual scale information minimization to realize the adaptive extraction of scale parameters.Based on this,combined with the shadow compensation factor,a multi-scale decision-level fusion strategy built on D-S theory of evidence was designed,and the levels of change intensity were further divided.The experiments show that the method is effective in solving the error detection problem caused by shadow,significantly improving the precision of change detection.

Key words: high resolution, remote sensing image, change detection, shadow compensation
