Medical optical imaging: Signal processing leads to new methods of detecting life-threatening situations [Special Reports]

Signal Processing Leads a Photographic and Imaging

Photography and imaging have been radically transformed over the past couple of decades in ways that 19th-century pioneers such as Louis-JacquesMandé Daguerre (Figure 1) and Henry Fox Talbot could have scarcely imagined. Traditional photography and imaging, rooted in chemical processes, have now largely given way to digital methodologies and technologies. The result has been faster, less expens...

Signal Processing for Medical Imaging

A new approach to detect Life threatening cardiac arrhythmias using Sequential spectrum of Electrocardiogram signals

This study evaluates the discriminative power of sequential spectrum analysis of the short-term electrocardiogram (ECG) time series in separating normal and subjects with life threatening arrhythmias like, ventricular tachycardia/fibrillation (VT/VF). The raw ECG time series is transformed into a series of binary symbols and the binary occupancy or relative distribution of mono-sequences (i.e. ...
