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, windows functions are symmetric around the middle of the interval ...
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 ...
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 ...
The Kaiser window, also known as the Kaiser–Bessel window, was developed by James Kaiser at Bell Laboratories. It is a one-parameter family of window functions used in finite impulse response filter design and spectral analysis. The Kaiser window approximates the DPSS window which maximizes the energy concentration in the main lobe [1] but ...
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 ...
Gabor transform. The Gabor transform, named after Dennis Gabor, is a special case of the short-time Fourier transform. It is used to determine the sinusoidal frequency and phase content of local sections of a signal as it changes over time. The function to be transformed is first multiplied by a Gaussian function, which can be regarded as a ...
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 ...
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 ...
