A robust high-resolution time-frequency representation based on the local optimization of the short-time fractional Fourier transform
Awal, Md Abdul; Ouelha, Samir; Dong, Shiying; Boashash, B. ( Elsevier Inc. , 2017 , Article)The Locally Optimized Spectrogram (LOS) defines a novel method for obtaining a high-resolution time-frequency (t,f) representation based on the short-time fractional Fourier transform (STFrFT). The key novelty of the LOS ... -
Automated detection of perinatal hypoxia using time-frequency-based heart rate variability features
Dong, Shiying; Boashash, Boualem; Azemi, Ghasem; Lingwood, Barbara E.; Colditz, Paul B. ( Springer Berlin Heidelberg , 2014 , Article)Perinatal hypoxia is a cause of cerebral injury in foetuses and neonates. Detection of foetal hypoxia during labour based on the pattern recognition of heart rate signals suffers from high observer variability and low ...
