What is the Name and briefly describe four types of noise?
1. White noise 2. Impulse noise 3. Echoes 4. Intermodulation
1 Which type of noise is most difficult to remove from digital signal?
Impulse Noise is the a noncontinuous noise and one of the the most difficult errors to detect because it occurs randomly. Like a lighting strike, the severity of the static across the radio could be so severe that you couldn't hear the music or like a vinyl record with a scratch, the pops and clicks associated with the hitting the scratch making the sound at that exact moment unrecoverable. Typically though, the impulse noise is an analog burst of energy.
What is the best description of impulse sound?
a lound noise such as a firework display
Which type of distortion occurs when a connection cable is inadequately insulated?
Impulse noise
What is the difference white noise and impulse noise?
Thermal noise occurs in all transmission media and all communication equipment, including passive devices. It arises from random electron motion and is characterized by a uniform distribution of energy over the frequency spectrum with a Gaussian distribution of levels. Noise. Impulse noise is noncontinuous, consisting of irregular pulses or noise "spikes" of short duration, broad spectral density, and relatively high amplitude.
What is noise in image processing?
Noise is static, kinda like when your tv screwes up
What has the author M J Coates written?
M. J. Coates has written: 'Impulse noise and sound exposure meters' -- subject(s): Industrial noise, Measurement, Noise, Sound analyzers
How does image noise relate to pitch in CT?
same
What is noise suppression in digital image processing?
removing noise from digital images. Noise is random color pixels which appears at digital images.
What is an image enhancer?
An image enhancer is a program or tool that can improve the quality of an image by increasing its contrast, sharpness, and other attributes. It can also be used to remove noise, artifacts, and other unwanted elements from an image.
What is 'smoothing filter' in digital image processing?
smoothing is a noise reduction technique that derives its name from the fact that it employs a simple, fast filtering algorithm that sacrifices noise suppression power in order to preserve the high spatial frequency detail (e.g. sharp edges) in an image. It is explicitly designed to remove noise spikes --- i.e. isolated pixels of exceptionally low or high pixel intensity (e.g. salt and pepper noise) and is, therefore, less effective at removing additive noise (e.g.Gaussian noise) from an image. biometrics@hotmail.com
Is decompression of an image introduce noise?
No, the decompression itself does not introduce any noise or loss of quality. In order to avoid loosing quality again, do not save the image in a format using lossy compression (like jpeg).
