Noise suppressing transmitter and noise suppressing method

The Journal of the Acoustical Society of America, 2000
Signals outputted from microphones 111 and 112 are inputted through filters 118 and 119 to noise suppressing sections A and B. One having smaller power is selected from output signals S107a and S107b by switching a selection switch SW in a signal power comparing section 117, to which the output signals S107a and S107b have been inputted, and a ...

Implementation for noise suppression in images

Image and Vision Computing, 1986
Abstract Random noise in images represents the primary problem for early visual processing. This paper describes an adaptive surface labelling technique (ASL) that suppresses image noise by using data-driven rules that concern surface continuity. The algorithm first obtains a global estimate of the noise distribution and then tries to fit a surface ...

Noise suppressing apparatus and noise suppressing method

The Journal of the Acoustical Society of America, 2006
Speech/non-speech determining section 103 makes a speech/non-speech determination of whether a speech spectrum is of a speech interval with a speech included or of a non-speech interval with only a noise and no speech included. Noise spectrum estimating section 104 estimates a noise spectrum based on the speech spectrum determined as the non-speech ...
