Image noise — Noise clearly visible in an image from a digital camera Image noise is random (not present in the object imaged) variation of brightness or color information in images, and is usually an aspect of electronic noise. It can be produced by the… … Wikipedia
Noise (disambiguation) — Noise is unwanted sound or signal. Noise may also refer different types of interference such as: Noise (audio), residual low level hiss or hum Noise (video), snow on video or television pictures Image noise, related to digital photography Noise… … Wikipedia
Noise reduction (disambiguation) — Noise reduction may refer to: Audio noise reduction Image noise reduction Soundproofing Record restoration See also Noise (disambiguation) This disambiguation page lists articles associated with the same title. If an … Wikipedia
Image editing — For the uses, cultural impact, and ethical concerns of image editing, see Photo manipulation. For the process of culling and archiving images, see Digital asset management. A colorized version of originally black and white photo, colorized using… … Wikipedia
Noise — This article is about noise as an unwanted phenomenon. For other uses, see Noise (disambiguation). NASA researchers at Glenn Research Center conducting tests on aircraft engine noise in 1967 In common use, the word noise means any unwanted … Wikipedia
Noise print — A noise print is part of a technique used in noise reduction. A noise print is commonly used in audio mastering to reduce the effects of unwanted noise from a piece of audio. In this case, the noise print would be a recording of the ambient noise … Wikipedia
Image Quality — is a characteristic of an image that measures the perceived image degradation (typically, compared to an ideal or perfect image). Imaging systems may introduce some amounts of distortion or artifacts in the signal, so the quality assessment is an … Wikipedia
Noise figure — (NF) is a measure of degradation of the signal to noise ratio (SNR), caused by components in a radio frequency (RF) signal chain. The noise figure is defined as the ratio of the output noise power of a device to the portion thereof attributable… … Wikipedia
Noise shaping — is a technique typically used in digital audio, image, and video processing, usually in combination with dithering, as part of the process of quantization or bit depth reduction of a digital signal. Its purpose is to increase the apparent signal… … Wikipedia
Image stabilization — (IS) is a family of techniques used to reduce blurring associated with the motion of a camera during exposure. Specifically, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of a camera or other imaging device. It… … Wikipedia
Image compression — is the application of Data compression on digital images. In effect, the objective is to reduce redundancy of the image data in order to be able to store or transmit data in an efficient form.Image compression can be lossy or lossless. Lossless… … Wikipedia
