The traditional method of kurtosis is calculating the kurtosis value in the time domain. The larger the obtained value is, the stronger the corresponding impact characteristic. Afterward, in order to characterize the period of the signal, the correlation kurtosis is proposed by combining the correlation coefficient and kurtosis. In this paper, the correlation kurtosis is calculated in the frequency...
For the blind estimation problem of period of the PN (Pseudo Noise) code and the combination code (combination of spread spectrum sequence and subcarrier sequence) in BOC (Binary Offset Carrier) signal with the residual carrier in the low SNR (signal-to-noise ratio), the method which combines the reprocessing of the power spectral density with matrix decomposition is developed. Firstly, the reprocessing...
Eye localization is a key step in many face analysis related applications. In this paper, we present a novel eye localization method based on a group of trained filters called correlation filter bank (CFB). We formulate the eye localization problem as an optimization problem with a well-defined cost function based on CFB. The CFB is trained with an EM-like adaptive clustering approach. The trained...
The development of a geometric invariant audio watermarking scheme without degrading acoustical quality is challenging work. This paper proposes a multi-bit spread-spectrum audio watermarking scheme based on a geometric invariant log coordinate mapping (LCM) feature. The LCM feature is very robust to audio geometric distortions. The watermark is embedded in the LCM feature, but it is actually embedded...
