Paper Abstract

We present novel enlarging methods of digital images based on Laplacian pyramid representation. First, 'direct method,' which is based on Laplacian pyramid representation, is proposed. The direct method is simple, however derive excellent enlargement results for only relative smooth regions of the image. Thus, we present the 'hybrid method' which is integrated the direct method and the Greenspan's method which is also based on Laplacian pyramid representation and has excellent property for enraging edge/detail regions. The effectiveness of the hybrid method is shown through a lot of experimental results.
