An audio watermarking algorithm via zero assigned filter banks
(2005)In order to identify the owner and distributor of digital data, a watermarking scheme for audio files is proposed in frequency domain. The scheme satisfies the imperceptibility and persistence requirements and is robust ... -
Contact-free measurement of respiratory rate using infrared and vibration sensors
(Elsevier BV, 2015)Respiratory rate is an essential parameter in many practical applications such as apnea detection, patient monitoring, and elderly people monitoring. In this paper, we describe a novel method and a contact-free multi-modal ... -
Directionally selective fractional wavelet transform using a 2-d non-separable unbalanced lifting structure
(2012)In this paper, we extend the recently introduced concept of fractional wavelet transform to obtain directional subbands of an image. Fractional wavelet decomposition is based on two-channel unbalanced lifting structures ... -
Leg motion classification with artificial neural networks using wavelet-based features of gyroscope signals
(2011)We extract the informative features of gyroscope signals using the discrete wavelet transform (DWT) decomposition and provide them as input to multi-layer feed-forward artificial neural networks (ANNs) for leg motion ... -
Wavelet merged multi-resolution super-pixels and their applications on fluorescent MSC images
(Institute of Electrical and Electronics Engineers Inc., 2015)A new multi-resolution super-pixel based algorithm is proposed to track cell size, count and motion in Mesenchymal Stem Cells (MSCs) images. Multi-resolution super-pixels are obtained by placing varying density seeds on ...
