摘要:
提出了采用多尺度Retinex突出图像中阴暗区域的信息, 采用Canny算子提取边缘, 编制程序提取图像中的阴暗区域, 将原图像阴暗区域的像素替换成多尺度Retinex增强图像的像素得到融合后的图像比原图像在阴影区域显示出更丰富的信息。 进而对遥感图像进行深人研究, 以埃及Giza金字塔中最大的Khufu金字塔阴影的几何分析, 确定太阳光的照射方位、仰角以 及观察点的方位与俯视角等信息描述的半自动提取特征信息融合彩色图像的技术, 在遥感图像地物信息提取中具有十分重大 的意义。
Abstract:
A new method has been revealed. The method highlights the information in the shaded region handled by Multi-scale Retinex (MSR) and extracts the closed shadow region by programs. It extracts object edges in the image using the Canny algorithm. The fused image is that the shadow regions in origin image are replaced by the same regions in the handled image using MSR. The new fused image has more information in the shadow region than that of origin image. Furthermore, it analyzes the more geometric information of new image such as irradiation placement, elevation angle of the sun light and irradiation placement, the looking down angle of the camera for an image of Khufu pyramid, which is the largest pyramid in Giza, Egypt. It describes a method that extracts the characteristic information by half-auto and that has great value in extracting land surface information for remote sensing image.
