iwspy is used to monitor a set list of nodes and record the link quality of each of them. The information gathered is the same as that available in /proc/net/wireless: quality of the link, signal strength and noise level. This information is updated each time a new packet is received, so each address of the list adds some overhead in the driver.
Linux also features iwspy, to read the signal, noise and quality of a wireless connection. Other related tools for configuring Ethernet adapters are: ethtool, mii-tool, and mii-diag in Linux and the command dladm show-link in Solaris. The ip suite has a similar purpose and is meant to replace the deprecated ifconfig. [6]
Imatest was founded by photographer/engineer Norman Koren in Boulder, Colorado in 2004 to develop software for testing digital camera image quality. Using Imatest software, a variety of image quality factors can be analyzed including Acutance (image sharpness), color response, image noise , dynamic range , tonal response, lens flare, lens ...
mountpoint — Check whether the directory or device is a mountpoint. mv — Move files. nbd-client — Connect to an NBD server. nc/netcat — Forward stdin/stdout to a file or network connection. netstat — Display networking information. nice — Run a command line at an increased or decreased scheduling priority. nl — Number lines of input.
Image quality can be assessed using objective or subjective methods. In the objective method, image quality assessments are performed by different algorithms that analyze the distortions and degradations introduced in an image. Subjective image quality assessments are a method based on the way in which humans experience or perceive image quality.
High school football enthusiasts who want to place a bet on a big game have no choice but to turn to an offshore site. Accepting a wager on high school sports is outlawed in Nevada and other U.S ...
The tattooed corpse of a woman was found bizarrely stuffed in a refrigerator dumped in some New Jersey woods — and cops say they need the public’s help identifying her.
Signal-to-noise ratio (SNR) is used in imaging to characterize image quality.The sensitivity of a (digital or film) imaging system is typically described in the terms of the signal level that yields a threshold level of SNR.
