摘要
Registration of multi-sensor images is an important part of image fusion. Because of the gray difference existing in multi-sensor image pairs, the registration problem of multi-sensor image is much difficult than that of single-sensor images. The existing STAR algorithm is appropriate for affine multi-sensor images, but is only applicable to images containing plenty of line segment features, because it is based on the extraction of line segments. Considering that the contour feature is more common than line segment feature in images, an enhanced STAR algorithm, called ESTAR, is presented according to contour extraction to overcome the limitation of the STAR algorithm in this paper.
