In a study published today, researchers from UH Mānoa, Rutgers University and the University of Haifa identified key and novel components of the molecular “toolkit” that ...
Spectrogram analysis of selected tremor signals using short-time Fourier transform and continuous wavelet transform
spectrogram wavelet transform broadband tremor
2015/10/8
Among a variety of spectrogram methods Short-Time Fourier Transform (STFT) and Continuous Wavelet Transform (CWT) were selected to analyse transients in non-stationary tremor signals. Depending on the...

Fast Slant Stack: A notion of Radon Transform for Data in a Cartesian Grid which is Rapidly Computible, Algebraically Exact, Geometrically Faithful and Invertible
Radon Transform Projection-slice theorem Sinc-Interpolation,
2015/8/21
We define a notion of Radon Transform for data in an n by n grid. It is based on summation
along lines of absolute slope less than 1 (as a function either of x or of y), with values at non-Cart...
MARKER-FREE REGISTRATION OF TERRESTRIAL LASER SCANS USING THE NORMAL DISTRIBUTION TRANSFORM
LIDAR Laser scanning Terrestrial Registration Matching
2015/8/7
The registration of scan data often uses special markers which are placed in the scene. This leads to a reliable registration
but the method is not very efficient. Therefore, we search for a re...
