英文摘要	引入一种基于关键点滤波(CrITICAl-POInT fIlTErS,CPf)的图像配准方法,并在最大后验概率(MAXIMuM A POSTErIOrI,MAP)框架下提出一种改进的集投影法(PrOJECTIOnS OnTO COnVEXSETS,MAP/POCS)混合算法。算法把POCS的残差约束集合加入到基于CPf图像配准的MAP正则算法中,在每次迭代重建中对重建图像的像素点进行约束,充分利用这三种算法的优点。实验结果表明,相比于传统的重建方法,该算法能够更有效地表达视频中的非平移运动,超分辨图像主观质量有明显改善。; An image registration method based on the critical-point filters is introduced in this paper,and an improved MAP/POCS hybrid algorithm based on the framework of MAP has also been proposed,the POCS residual set of constraints is added to the reconstruction algorithm of MAP based on the critical-point filters registration method joined the adaptive regularization parameter so that it can take advantage of the three algorithms.After the test,the results show that compared with the traditional methods,the algorithm of this paper can express the non-translational motion more effectively and the quality of the super-resolution images has been improved obviously.; 国家自然科学基金项目(61102135); 中国博士后科学基金项目(2012M511433)
