摘要: 摘 要 本文提出了一种在临界抽样条件下基于2D DCT的二维实值离散Gabor变换(2D RDGT),介绍了其快速算法。并比较了该变换与二维复值离散Gabor变换(2D CDGT)的算法复杂性。

Abstract: Abstract A 2D real-valued discrete Gabor transform(2D RDGT) based on DCT in the case of critical sampling condition is defined in this paper and a corresponding fast algorithm is presented. In the paper, we also compared the complexity of algorithm between the 2D real-valued discrete Gabor transform(2D RDGT) and the 2D complex- valued discrete Gabor transform(2D CDGT) .
Key words: 2D Real-valued discrete Gabor transform, 2D DCT, critical sampling
