Abstract

In this paper, we address the problem of generating high-resolution (HR) image from a single low-resolution (LR) image, which is called image super-resolution (SR). Recently learning-based SR with sparse coding (SC), locality-constraint linear coding (LLC) and so on has been explored, and achieve acceptable performance. However, the conventional learning based methods cannot directly deal with a blurred LR input, which is usually considered as another research line of de-blurring, and extremely difficult to implement for real applications. This paper proposes to firstly estimate the blurring degree of an input image, and then generate the adaptive codebook (dictionary) for learning-based SR, which can simultaneously achieve the de-blurring and high-resolution image in the learning framework. We integrate our previous LLC based SR with the adaptive de-blurring procedure. Experimental results show that our proposed strategy can reconstruct the HR images more accurately than conventional methods, and its processing time is much faster.
