基于有限内存Broyden-Fletcher-Goldfarb-Shanno优化算法的图像非刚性配准方法

图像配准可以分为刚性配准和非刚性配准两类,图像非刚性配准是图像处理研究的热点和难点,其中的参数模型往往转化为无约束优化问题的求解,当参数数目较大时求解比较费时,提高此类算法效率的关键之一是减少迭代算法中矩阵的计算量和存储量.本文研究了一种非刚性配准方法,该方法应用Basic样条自由变形模型,此模型改变控制点只影响其附近...

Non-rigid registration based on Basic-spline free form deform and limited memory Broyden-Fletcher-Goldfarb-Shanno optimal algorithm

Image registration is one of the basic tasks of image processing,which is widely used in military,remote sensing,medicine,computer vision,pattern recognition and other fields.Image registration is to make an image consistent with another image on the corresponding point,surface,or pixel values to using geometric transform in the same space,which will be a variety of modes of image information fusion into a new image.Multiple images from the same object are taken by the same or different sensors,at different...
