A-Bayesian-Adaptive-Basis-Algorithm-for-Single-Pa - Traditional single particle reconstruction methods use either the Fourier or the delta function basis to represent the particle density map. We propose a more flexible algorithm that adaptively chooses the basis based on the data. Because the basis adapts to the data, the reconstruction resolution and signal-to-noise ratio (SNR) is improved compared to a reconstruction with a fixed basis. Moreover, the algorithm automatically masks the particle, thereby separating it from the background. This eliminates the need for ad-hoc filtering or masking in the refinement loop. The algorithm is formulated in a Bayesian maximum-a-posteriori framework and uses an efficient optimization algorithm for the maximization. Evaluations using simulated and actual cryogenic electron microscopy data show resolution and SNR improvements as well as the effective masking of particle from background,2013-04-05 22:04:51,下载7次
Discret-Wavelet-Transform-got-Daub2-by-Santhana-R - y=d2wavelet(x,Fs,level) does the 2nd order Daubechies Wavelet Transform of signal x with a sampling frequency Fs and the DWT is decomposition is done upto a level
It returns the matrix of all decompositions and the final approximations.
Instead of using the matlab s inbuilt DWT function, this file explains the algorithm for DWT. Mostly useful for learning & academic purposes.
For other wavelets, the filter values alone can be changed or WFILTERS can
be used.
The function basically is for Condition Monitoring of rotating equipments by vibration based bearing fault diagnosis by the author.
Example:
clear all
t=[0:0.0003:8*pi]
x=sin(5000*t)+sin(1000*t)
x=x(1:2^16)
level=5 Fs=1/0.003

Feature-Extraction-Using-Multisignal-Wavelet-Tran - I am simply extracting three types of features from the wavelet transform coefficients, these include: energy, variance and waveform length. You can modify and extract any types of features as you need.
** You need the wavelet toolbox to run this code.

Morlet-Wavelet-Kernel-by-Marcelo-Cicconet.zip - The Morlet wavelet (or Gabor wavelet) is a wavelet composed of a complex exponential (carrier) multiplied by a Gaussian window (envelope). This wavelet is closely related to human perception, both hearing and vision.,2013-04-05 21:42:13,下载25次
HE-de-Oliveira--legdinfo.zip - Spherical harmonic wavelets or Legendre wavelets are compactly supported wavelets, which are derived from Legendre polynomials. These wavelets are suitable for problems of spherical symmetry since they correspond to the colatitudinal part of "spherical harmonics" in spherical polar coordinates.
