random noise造句
1 The image has plenty of random noise, so at first the noise should be reduced. 2 It is a general trend to combine the random noise technology and the UWB imaging technology. 3 Then, The WVD function's mechanism of suppressing additive random noise in stationary random process is analyzed theoretically. 4 Random noise are minished by using method of difference and flatness . 5 And the algorithm is insensitive to the random noise when the weight function is an odd function of gray of an image. 6 First, assume that sources of random noise in the amplifiers are mutually independent. 7 Random noise, such as crackling in a receiver or specks on a television screen, produced by atmospheric disturbance of the signal. 8 The random noise occurs in the process of image acquisition and transportation should be filtered. 9 According to the existed type of random noise in fingerprint image, we proposed an integrated denoising algorithm based on mid-value filtering and wavelet transform of fingerprint image. 10 All markets have a certain amount of random noise, or quick counter trend moves. 11 When applied in airborne imaging surveillance, UWB random noise radars have their special merits. 12 The influence on the measured velocity of random noise, cross sensitivity and alignment errors is discussed. 13 Without an intimate knowledge of haemoglobin it would be easy to dismiss them as random noise. 14 The results demonstrate the cross correlation filter not only can suppress random noise in GPR signal but also confirm exactly the onset of reflection wave. 15 Before spectral subtraction, stationary wavelet filtering is made for noisy signal and noise model, which can effectively eliminate "music noise" caused by random noise spectral. 16 The parameters contain impulse noise, memory effect, scan correlated shift, coherent noise, random noise, dropped lines, inoperable detectors, saturated detectors, MTF, system resolution. 17 Using correlation means in testing phase response can reduce random noise and improve precision of phase test. 18 Signal to Noise Ratio ( SNR ) : The ratio of the signal to the random noise setdata. 19 In digital terrestrial television system, there is much burst and random noise in the broadcasting channel, and burst noise is more harmfully than random noise. 20 Being different from the existing measurement method for A/V delay, the system does not produce random noise to interfere audio test, and does not need video test signal to interrupt live program. 21 Correlated random series is the mainly tool for describing the property of random noise, clutter and jamming, which is widely used in satellite communications, normal radar and spaceborne radar. 22 This artical presents a new general and flexible solution to real - time errorcode generator, laking random noise and burst noise as examples. 23 In order to avoid the error decision in the presence of noise, the median filtering and connected region labeling is operated to eliminate the random noise and false stationary regions. 24 Because all the atoms move coherently, the information doesn't dissolve into random noise and get lost. 25 Finally, by using residuals instead of periodic pulse excitation - random noise binary excitation, s the quality of synthesized speech has been some upgrading. 26 This method was checked using both synthetic seismogram and real seismic record. The check proved K-L transform feasible in removing random noise and coherent noise.
