摘要
本文通过仿真实验研究了单帧低分辨率图像的超分辨率重建技术。首先,阐述了用于单帧超分辨率重建的插值法、IBP法和POCS法,然后通过matlab7.0仿真程序验证了双三次插值法、双线性插值法、POCS法和IBP法,并根据仿真实验的结果分析这些方法重建效果的好坏。实验结果表明,实验结果证明,双线性插值方法的重建结果要优于双三次插值的重建结果;IBP的重建效果要优于POCS方法;对于IBP和POCS来说,2种方法都能获得较好的重建结果,并且用于图像的帧数越多,重建的效果越好;此外,客观评价方法与主观评价方法有时不能获得相同的评价结果,但在多数情况下,客观评价方法都能取得与主观评价方法一致的结果。
The aim of this study was to develop a super-resolution reconstruction technology of singleframe low-resolution images.Firstly,super-resolution reconstruction method of low-resolution images was discussed,namely,about the interpolation,IBP and POCS methods.The methods were then verified by simulation with Matlab 7.0 and the reconstruction effects obtained by these methods were analyzed.The experiment results show that all of the effects obtained by the three methods are better than that before reconstruction,in which the bi-cubic method may have better reconstruction effect than the linear-interpolation,and for IBP and POCS,the more the number of the images was used for reconstruction,the better the effect is.
