Abstract
Bicubic interpolation is a standard method in image interpolation field because of its low complexity and relatively good results. But as it only interpolates in horizontal and vertical directions, edges easily suffer from artifacts such as blocking, blurring and ringing. This paper proposed a new method of image super-resolution which is named directional bicubic interpolation. According to local strength and directions, different ways are used to interpolate missing pixels. Compared with bicubic interpolation, the proposed method can preserve sharp edges and details better. Experiment results show that the proposed method is better than existing edge-directed interpolations in terms of subjective and objective measures, and its computation complexity is low.
