Image noise can be generated by adding random variations to pixel values in an image. This can be achieved using various noise models, such as Gaussian noise, which adds values sampled from a Gaussian distribution to each pixel, or salt-and-pepper noise, which randomly replaces some pixels with maximum or minimum values. Software tools and libraries like Python’s NumPy or OpenCV can be used to implement these techniques programmatically. Adjusting the parameters of the noise model allows for control over the noise intensity and characteristics.

What is impulse noise in an image?
Impulse noise is a short duration noise.
What form of noise interference is problematic in cable modem uploads?
Noise that household appliances generate
What generates more noise ac motor or dc motor?
dc motors generate more noise.
What is noise in image processing?
Noise is static, kinda like when your tv screwes up
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.
Correlated and uncorrelated noise?
If I have two source of noise let as say two laser diodes so the pink noise that generate fro both of them is it correlated or uncorrelated
What is the well called to make the image clearer?
The term for enhancing image clarity is "image enhancement." This process involves improving the visual quality of an image by making it sharper, adjusting contrast, brightness, or reducing noise. Techniques like sharpening filters, contrast adjustments, and noise reduction are commonly used for image enhancement.
Can the alternator be the problem for the audio?
yes the alternator can generate noise or whine in the speakers.
What is image noise in the radiograph?
Image noise in a radiograph refers to the random variations in pixel values that can obscure or distort the true representation of tissues or structures within the image. It can result from various factors, including electronic interference, patient movement, or insufficient radiation exposure. High levels of noise can reduce the clarity and diagnostic quality of the image, making it challenging for radiologists to identify abnormalities. Reducing noise enhances the visibility of important details in the radiograph.
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
