| 摘 要： | 本文将一维子序列FFT内插算法推广到二维,并给出二维子序列FHT内插算法对于需要以低取样率存贮或传输图象和重构图象质量要求较高的场合,本算法特别有用。同时,新算法还适合并行处理。

| Abstract: | The subsequence interpolation algorithm using FFT has been generalized for interpolation of 2-D signal. The subsequence interpolation algorithm using FHT for 2-D signal is proposed. The algorithm will be useful when one needs to store or transmit an image sampled at lower rate and reconstruct it later with better quality. This new algorithm is more suitable for parallel processing. |
