Abstract: Image mosaic is one of the active techniques of IBR. Its core is the image registration. To register two images, the coordinate transformation between a pair of images must be found. In this paper, a multiresolution feature-based method is developed to efficiently estimate an eight-parametric projective transformation model between pairs of images. The proposed method is tested and worked well

摘要： 图像镶嵌是IBR 研究的热点技术之一，而其核心问题是图像配准。为了配准两帧图像，必须寻找两帧图像对之间的坐标变换。该文提出的基于多分辨率特征的方法有效地实现了图像间的8-参数投影变换模型的估计。该方法经测试效果良好。
