An AM-FM model for motion estimation in atherosclerotic plaque videos
(2007)We present new multidimensional Amplitude-Modulation Frequency-Modulation (AM-FM) methods for motion estimation. For a single AM-FM component we show that the optical flow constraint leads to separate equations for amplitude ...

Decoding algorithm and architecture for BCH codes under the Lee metric
(2008)The Lee metric measures the circular distance between two elements in a cyclic group and is particularly appropriate as a measure of distance for data transmission under phase-shift-keying modulation over a white noise ...

Direct quadrature phase shift keying modulation using compact wideband six-port networks
(2012)In this study, the operation of a compact six-port network operating as a quadrature phase shift keying (QPSK) modulator with a wide operational bandwidth is presented. The modulation has been accomplished using two types ...

Effects of Ge concentration, boron co-doping, and hydrogenation on fiber bragg grating characteristics
(2005)In this paper, we compare photosensitivity, refractive-index modulation depth, spectral bandwidth, and excess loss through the inscription of fiber Bragg gratings in unloaded and hydrogen-loaded fibers with low- or ...

Evaluation of spatial dependence matrices on multiscale instantaneous amplitude for mammogram classification
(Springer Verlag, 2015)Breast cancer is the most common cancer in women. Mammography is the only breast cancer screening method that has proven to be effective. Mammographic breast density is increasingly assessed towards the development of more ...

Extension and application of an algorithm for systematic identification of weak coupling and partitions in dynamic system models
(2009)This paper reviews and extends a technique to detect weak coupling (one-way coupling or complete decoupling) among elements of a dynamic system model, and to partition and reduce models in which weak coupling is found. The ...
