There are four main variants of 4:2:0 schemes, having different horizontal and vertical sampling siting relative to the 2×2 "square" of the original input size. [15] In MPEG-2, MPEG-4, and AVC, Cb and Cr are taken on midpoint of the left-edge of the 2×2 square. In other words, they have the same horizontal location as the top-left pixel, but ...
The sensitivity of an electronic device, such as a communications system receiver, or detection device, such as a PIN diode, is the minimum magnitude of input signal required to produce a specified output signal having a specified signal-to-noise ratio, or other specified criteria. In general, it is the signal level required for a particular ...
Unicode input is method to add a specific Unicode character to a computer file; it is a common way to input characters not directly supported by a physical keyboard. Characters can be entered either by selecting them from a display, by typing a certain sequence of keys on a physical keyboard, or by drawing the symbol by hand on touch-sensitive ...
Context sensitivity is ubiquitous in current graphical user interfaces, often in context menus. A user-interface may also provide context sensitive feedback, such as changing the appearance of the mouse pointer or cursor, changing the menu color, or with auditory or tactile feedback.
Variance-based sensitivity analysis (often referred to as the Sobol’ method or Sobol’ indices, after Ilya M. Sobol’) is a form of global sensitivity analysis. [ 1 ] [ 2 ] Working within a probabilistic framework, it decomposes the variance of the output of the model or system into fractions which can be attributed to inputs or sets of inputs.
Flick Stick is a video game control scheme designed for gyroscopic game controllers.The Flick Stick control scheme is primarily designed for 3D shooter games with the intent of bringing the perceived advantages of mouse aiming to controllers, while addressing shortcomings of traditional first-person shooter controller schemes.
The sensitivity function tells us how the disturbances are influenced by feedback. Disturbances with frequencies such that | S ( j ω ) | {\displaystyle |S(j\omega )|} is less than one are reduced by an amount equal to the distance to the critical point − 1 {\displaystyle -1} and disturbances with frequencies such that | S ( j ω ...
In structured cabling, crosstalk refers to electromagnetic interference from one unshielded twisted pair to another twisted pair, normally running in parallel. Signals traveling through adjacent pairs of wire create magnetic fields that interact with each other, inducing interference in the neighboring pair.
