In this paper, we propose a novel image interpolation method to obtain high resolution (HR) images. In the proposed method, the image is decomposed using a bilateral filter into the detail and base layers which represent textual and structural information of images, respectively. Then, the detail layer is interpolated and amplified to obtain a clear edge without blurring. Since the base layer contains the structural information of the image, this layer is enlarged by an edge-preserving interpolation method to reduce jagging. Experimental results show that the proposed algorithm outperforms the conventional methods in terms of blurring and jagging.
