Speaker recognition plays an important role in speech processing and classification. In this paper, we propose a features extraction method using Perception Auditory Factor to improve the performance of speaker recognition in noisy environment. After the speech enhancement based on auditory perception characteristic and the 2-dimension enhancement for spectrogram, speech distribution is obtained from...
Image searching and authentication have become important issues for the digital world. Image hashing technique has been proposed to meet them. In this paper, a self-synchronized image hashing algorithm resistant to rotation is presented. In the algorithm, the features of the image are extracted by Scale Invariant Feature Transform(SIFT) algorithm. Then a cyclic matrix are generated from the features...
Image searching and authentication have become strong requirements in the digital world. Image perceptual hashing has been proposed to meet them. In this paper, a rotation resilient image hashing algorithm is presented. In the algorithm, the position information of original image is extracted to adjust the rotation. Then the features of the image are extracted by contourlet transform. The key-dependence...
