The FSC is the commonly accepted method to estimate the resolution limit (usually defined at a correlation of 0.5) of threeヾimensional (3D) reconstructions from Cryo Electron Microscopy Cryo〦lectron...Project GutenbergSpringer Berlin Heidelberg...
The first is the local FSC (Fourier shell correlation) between the full map and the model, while the second is calculated between the half maps normally used in typical single particle analysis workflows. We call the quality measure "FSC-Q", and it is a quantitative estimation of how much ...

The Fourier shell correlation2 (FSC) between the reconstructions and the model further confirms that the GENFIRE resconstruction is superior at all spatial frequencies compared to other algorithms. This simulation was also performed with no noise and higher noise (Supplementary Figs 2 and 3). In ...
Similar to the convolution operation, cross-correlations are also easily implemented in the frequency domain as Z(f)=X(f)∗Y(f)Z(f)=X(f)∗Y(f), where ∗∗ denotes complex conjugate. By being able to split signals into their constituent frequencies, one can easily block out ce...

Bo Ren [10] calculated 30-order Fractional Fourier phase features and Gabor features separately to calculate statistical features, then used DMCCA [11] (Discriminative Multiple Canonical Correlation Analysis) to perform a features fusion, and obtained a good classification accuracy.

and can be seen in T2*-weighted MRI time series data [2,3]. These time series data, referred to as blood-oxygen-level-dependent (BOLD) fMRI, typically have a low temporal signal-to-noise-ratio (SNR) [4] as well as high temporal correlation [5] that can make them difficult to ...
The amplitude and phase profile of the object is then recovered from the cross-correlation terms by computing the Fourier transform of the measured hologram. The resolution in this case depends on the size of the reference structures in addition to the coherence and photon energy of the source,...
