Sentence examples for frequency enhancement from inspiring English sources
To study the appearance of the architectural distortions, two enhancing filters were applied to the images: a morphological high frequency enhancement filter (MoF) designed to enhance fiber-like tissues and a Laplacian of Gaussian filter (LoG) to enhance high frequency patterns inside the breast tissues.
This frequency enhancement is explained using theoretical calculations.
We describe the fundamental limit of resonance frequency enhancement and generalize these results to oscillators of all kinds.
Experimental results show correct noise-shaping for sampling frequencies up to 16 MHz, which means a significant operation frequency enhancement as compared to previously reported SI ΣΔ Modulators.
As a result, we get smaller speckle patterns on the final assembled image and a spatial frequency enhancement with respect to the decoded image obtained with the conventional procedures.
In the previous literature binary edge detection algorithms, e.g. Sobel and Canny edge detection, are extensively used for spatial frequency enhancement.
Thus, the proposed adaptive enhancement algorithm is expressed by: {E}_{ k)}^Hkern0.5em =kern0.5em alpha (k){h}_{ k)}^Hkern0.5em -kern0.5em left(1kern0.5em -kern0.5em alpha (k)right){e}_{ k)}^H, (21 where α(k) is a decay function with k such that the high-frequency enhancement will be gradually reduced and the error compensation can be increased after iterations.
The core spectrogram shows an initially strong mid-frequency enhancement.
After 2 hours, there is a strong onset of low-frequency enhancement for both the shell and the core.
The active transport that is present in the shell but missing in the core, combined with the presence of low-frequency enhancement that is common to both, suggests a metric that is the logical AND of both of the features to create an "apoptotic" index that quantitatively captures this feature.
Our data, showing increases in both amplitude and frequency in juvenile mEPSCs but only frequency-enhancements in adult mEPSCs, seem to suggest that the age of the animal may also play a role in the locus of the plasticity at hippocampal excitatory synapses in response to activity-deprivation.
