Most popular window functions are similar bell-shaped curves. In signal processing and statistics, a window function (also known as an apodization function or tapering function [1]) is a mathematical function that is zero-valued outside of some chosen interval. Typically, window functions are symmetric around the middle of the interval ...
Short-time Fourier transform. The short-time Fourier transform ( STFT) is a Fourier-related transform used to determine the sinusoidal frequency and phase content of local sections of a signal as it changes over time. [1] In practice, the procedure for computing STFTs is to divide a longer time signal into shorter segments of equal length and ...
Window (computing) In computing, a window is a graphical control element. It consists of a visual area containing some of the graphical user interface of the program it belongs to and is framed by a window decoration. It usually has a rectangular shape [1] that can overlap with the area of other windows. It displays the output of and may allow ...
The Hann function is named after the Austrian meteorologist Julius von Hann. It is a window function used to perform Hann smoothing. [1] The function, with length and amplitude is given by: [a] For digital signal processing, the function is sampled symmetrically (with spacing and amplitude ): which is a sequence of samples, and can be even or ...
Lanczos filtering and Lanczos resampling are two applications of a mathematical formula. It can be used as a low-pass filter or used to smoothly interpolate the value of a digital signal between its samples. In the latter case, it maps each sample of the given signal to a translated and scaled copy of the Lanczos kernel, which is a sinc ...
The window decoration is either drawn by the window manager or by the client. The drawing of the content is the task of the client. In computing, a windowing system (or window system) is a software suite that manages separately different parts of display screens. [1] It is a type of graphical user interface (GUI) which implements the WIMP ...
borderless fullscreen windowed An option featured in many modern PC games and moddable into others in which a game appears fullscreen but is actually running in a maximized window. Since the game does not take full control of the output device, it confers benefits such as seamless task switching and automatic vertical synchronization. boss
Desktop Window Manager ( DWM, previously Desktop Compositing Engine or DCE) is the compositing window manager in Microsoft Windows since Windows Vista that enables the use of hardware acceleration to render the graphical user interface of Windows. It was originally created to enable portions of the new "Windows Aero" user experience, which ...
