摘要: 本文將一維子序列FFT內(nèi)插算法推廣到二維,并給出二維子序列FHT內(nèi)插算法對(duì)于需要以低取樣率存貯或傳輸圖象和重構(gòu)圖象質(zhì)量要求較高的場(chǎng)合,本算法特別有用。同時(shí),新算法還適合并行處理。

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. -
