Digital Image Enlargement Based on Kernel Component Estimation
p. 97-108
Abstract
A new approach for enlarging digital images is proposed. In existing approaches, the assumed reducing operators must be suitable ones for the methods, which means that desirable results are not obtained in other situations. Therefore, an enlargement scheme that can appropriately take reducing operators into account is needed. In this paper, we propose a new enlargement method that can be used for any reducing operators based on the framework of image restoration problems and estimation of the component that belongs to the kernel space of the reducing operator by using statistical properties of natural images.
