Abstract :
This article proposes a new interpolation method, called the error-amended sharp edge (EASE) scheme. EASE is a modified bilinear method which tries to amend the interpolation error in an edge-adaptive way by employing the interpolation error theorem. The resulting scheme has proved to result in zoomed images having sharper edges than bilinear, C1-bicubic, and C2-bicubic interpolation methods. EASE is similarly efficient as cubic interpolation methods and can be implemented with ease.
