Abstract :
A new interpolation-based scheme for image expansion is introduced. In the proposed method, the fidelity and sharpness of edges in the expanded image is emphasized. This is achieved by applying edge-directed interpolation and edge sharpening operations. Compared with other methods, our method provides natural and sharp expanded images with light computational cost
