Several methods for image enlargement have been studied. However, their performance is not enough because they cannot correctly estimate high frequency components that are missed when the target image is sampled. Therefore, this paper proposes a new image enlargement method using an Iterated Function System(IFS). The IFS generates images from an arbitrary initial image by iteration ofcontractive mappings. Noting a property that the resolution of the target image do not affect the parameters which determine the contractive mappings, the proposed method applies the IFS to the image enlargement. Futher, the proposed method modifies the determination scheme of the parameters of the contractive mappings and the generation scheme of the target image. Then, the problem caused by the difference of the self-similarity between the target image and the original enlarged image, can be solved. Consequently, the accurate image enlargement can be achieved. |
