【摘要】 为了提高图像配准的稳定性和可靠性,研究了尺度不变特征变换(Scale Invariant Feature Transform)算法在图像配准中的应用。在尺度空间,尺度不变特征变换算法对图像的平移、旋转和仿射变换具有不变性。将该方法应用到图像配准中,验证了尺度不变特征变换算法的稳定性和可靠性,甚至对任意拍摄角度的图像都具有稳定的匹配能力。更多还原

【Abstract】 In order to improve the stability and reliability of image matching,application of the scale invariant feature transform(SIFT) algorithm to image matching was studied.Characteristics of SIFT are invariable,which are the translation,rotation and affine of image in the scale space.The simulation results prove that SIFT algorithm is stable,reliable and performs well for image of arbitrary angle by applying SIFT to image matching.更多还原
