摘要 分析了中心 /环绕Retinex算法在阴影消除上的局限性 ,并提出了一种新方法———边缘模糊Retinex ,用于城市彩色航空影像中的阴影消除。首先利用阴影检测算法 ,把图像分割为阴影区域和非阴影区域。然后对阴影边缘进行模糊化。并利用中心 /环绕Retinex算法 ,分别处理模糊化后的图像阴影区域和非阴影区域。最后将结果合并 ,并去模糊。实验表明该方法取得了较好的效果。 The limitation of the SSR algorithm is analyzed when applying to shadow eliminating, and a new approach eliminating shadows in colored aerial image,called Edge-Fuzzied-Retinex, is proposed. The color image is first segment into shadow region and non-shadow region using a shadow detection algorithm with the region border fuzzied,then the SSR algorithm is appied to the two regions, respectively,finally the two are comined together.The results demonstrate that such approach workes well.
