Paper Abstract

Extraction of high-resolution face image is crucial to detect suspect from low-resolution surveillance videos. Though previously published super-resolution image reconstruction techniques could produce a qualified high-resolution image from a set of simulated low-resolution images, but the reconstructed image from real low-resolution videos is always blurring. Two main reasons contribute for this: the process of image registration is ill-posed in nature and the sub-pixel information provided by the real video sequences is far less sufficient. In this paper, a joint image registration and face pattern-based high-resolution image reconstruction algorithm was proposed to tackle these two problems. Experimental results are also provided to demonstrate the effectiveness of the proposed algorithm.
