Multi-Frame Super-Resolution is a technique which attempts to reconstruct high-resolution image by fusing a number of low-resolution images. Therein, high-accuracy registration for the input low-resolution image set is required for reconstruction a clear high-resolution image. The conventional registration approaches for Multi-Frame Super-Resolution such as Iterative Back Projection and LK optical flow methods, can obtain accurate parameters for tiny translation or rotation movement between images. However, for large movement especially in rotation, there are still no efficient methods for reconstructing high-resolution image. Therefore, in this paper we proposed a new method using Rotation Invariant Phase Only Correlation, which can estimate large rotation parameter, and then follow the Iterative back Projection method for obtaining the high accurate parameters. Experimental results show that the reconstructed high resolution images by our proposed approach are much better than those by interpolation techniques. |
