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) .
