comparing the variance of the residual signal to another predetermined threshold, determining a filter strength for the macroblock based on one or more of factors such as correlation, motion vector size and variance of the residual signal and filtering the macroblock using a filter of appropriate str...
摘要: A three-dimensional filter that addresses various types of noise is described. This filter uses both spatial and temporal characteristics of the video signal in the filtering process. Additionally, the filter is able to maintain edge fidelity within in images in the video signal.收藏...
A pop filter is a mesh screen that is placed in front of a microphone to minimize plosive sounds like "p" and "b" sounds. Windscreens are often made of foam or furry material, reducing wind noise and other air disturbances. These tools are very helpful for reducing background noise. 4...
But remember, you cannot completely remove background sound of traffic or people, which is louder or at the same frequency as the main speech, music, or audio. To fix such loud background noise, first use a Notch Filter feature followed by Noise Reduction in Audacity. Notch filterhelps to ...
