摘要
提出了基于多尺度Retinex(MSR)和边缘提取实施彩色图像融合的一种新方法。多尺度Retinex算法具有突出图像中阴暗区域信息的功能,采用边缘检测的方法提取图像中阴暗区域,将原图像阴暗区域的像素替换成多尺度Retinex增强图像的像素实现彩色图像融合,得到的新图像信息更丰富。在提取闭合区域时,提出了区分真断点和准断点的技术,改进了闭合边缘提取的方法。进而对融合的新图像进行了深入研究,获得埃及Giza金字塔中最大的Khufu金字塔阴影的几何信息。
A new method is proposed to enhance color image, based on Multi-Scale Retinex （MSR） and closed regions extraction. It highlights the information in the regions of the shadow using MSR and extracts the closed regions of the image by edge detection. The image fusing is that the regions of shadow in original image is replaced by the same regions of the handled image using MSR. The new fusing image has more abundant information than that of original image. When the closed regions were extracted, the real-broken points or quasi-broken points were judged with the method presented in this paper. Furthermore, the much geometric information of Khufu pyramid of Giza pyramids remote sensing image in Egypt was obtained.
