| Abstract(in English) | Enlargement of digital image is a prime technique in the digital image processing field. Generally, an image enlargement is realized by linear interpolation method. However, the enlargement image by linear interpolation will appear blurred. The heavy blurred areas, those include high-frequency components, such as step-edge and peaks. In order to realize the edge-preserving and the peak-creating interpolation, we have introduced the concept of the warped distance among the pixels and biasing the signal amplitude. This paper presents a novel interpolation with only biasing of the signal amplitude. The proposed method can create the peak point of concavo-convex shape signals. Furthermore, the proposed biasing method can preserve the signal edge. Thus, it is not necessary to combine the biasing and the warping. |
