Video4Linux (V4L for short) is a collection of device drivers and an API for supporting realtime video capture on Linux systems. [1] It supports many USB webcams, TV tuners, and related devices, standardizing their output, so programmers can easily add video support to their applications.
CoaXPress (CXP) is a digital interface standard developed for high-speed image data transmission in machine vision applications. The name is a portmanteau of 'express' and 'coaxial' to emphasize CoaXPress is faster than other standards (e.g. Camera Link or GigE Vision) and uses 75 ohm coaxial cables as the physical transmission medium.
In holography, the space–bandwidth product determines the resolution and quality of the reconstructed holographic image. The SBP sets a limit on the amount of information that can be recorded and reconstructed. In digital holography, the SBP of a holographic imaging system can be calculated by analyzing at the recorded interference pattern. [3]
GigE Vision comes of age: advantages like high bandwidth, cable length, widespread use and network ease make it a major interface (2009) A high resolution smart camera with GigE Vision extension for surveillance applications (2008) A high speed robot vision system with GigE vision extension (2011)
The Rayleigh bandwidth of a simple radar pulse is defined as the inverse of its duration. For example, a one-microsecond pulse has a Rayleigh bandwidth of one megahertz. [1] The essential bandwidth is defined as the portion of a signal spectrum in the frequency domain which contains most of the energy of the signal. [2]
The consumed bandwidth in bit/s, corresponds to achieved throughput or goodput, i.e., the average rate of successful data transfer through a communication path.The consumed bandwidth can be affected by technologies such as bandwidth shaping, bandwidth management, bandwidth throttling, bandwidth cap, bandwidth allocation (for example bandwidth allocation protocol and dynamic bandwidth ...
Bandwidth test software is used to determine the maximum bandwidth of a network or internet connection. It is typically undertaken by attempting to download or upload the maximum amount of data in a certain period of time, or a certain amount of data in the minimum amount of time.
Some other computer architectures use different modules with a different bus width. In a single-channel configuration, only one module at a time can transfer information to the CPU. In multi-channel configurations, multiple modules can transfer information to the CPU at the same time, in parallel.
