Analysis and Comparison of Various Image Downsampling and Unsampling Methods
Abdou S. Youssef
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.
