I is the selected noisy window, T is the same window illustrating the detected edge, and P is the computed gradient magnitude.
But there had also been looser, noisier occurrences — windows broken, yogurt thrown — sometimes at the edge of the organized gatherings, like the sit-in at the Central Bank, and a disturbance on New Year's Eve during which protesters cut through a cable carrying live television pictures of the annual gathering where political leaders discuss the year ahead over wine and spiced herring.
Firstly, impulse noise is detected by the proposed efficient method, and one of 3 × 3, 5 × 5, and 7 × 7 dynamically weighted median filters (DWMs) is applied according to the number of noisy pixels in windows.
Given the stochastic approximation nature of the proposed approach, creating and updating a histogram of the errors in the window or using Parzen estimators [45] makes sense but it will be noisy because the window is small.
Firstly, the noisy speech is windowed and transformed into frequency domain by DFT.
The power spectrum of the noisy signal in window can be represented by (2).
FMRI gives a noisy and incomplete window on neural mechanisms.
While a short time window led to noisy turn probability estimates, long time windows led to undesirable averaging effects.
On that ledge, a carved wood bathtub made of caldén (a native Argentine wood) takes center-stage in front of floor-to-ceiling glass windows, with noisy electric-operated curtains opening onto balconies.
These results show that a longer window length results in a more-or-less stationary spectrum (which can be quite noisy), whereas a smaller window length produces a single instantaneous frequency with complicated time variations.
Conventional adaptive filters, on the other hand, extend window size when there is no noise-free pixel in window or median of window is a noisy pixel.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
