Abstract

Downsampling and upsampling are widely used in image display, and jointly used in compression and progressive transmission. In this paper we examine new down/upsampling methods using both frequency response analysis and experimental evaluation. Our findings show that binomial filters and some biorthogonal wavelet filters are among the best filters for down/upsampling, and significantly outperform the standard down/upsampling methods.
