In this paper, an edge-directed interpolation is proposed using edge map analysis. Conventional algorithms have various disadvantages (edge blurring effect, excessive computational complexity, etc.) by performing interpolation without distinguishing between flat and edge regions. Therefore, it is possible to overcome the drawbacks and limitations of the existing algorithms by applying the optimal interpolation technique to the flat area and the edge area through edge map analysis. The comparison of objective and subjective experimental results shows that the proposed algorithm shows better performance than the existing
