Filter (Optik) — Optische Filter selektieren die einfallende Strahlung nach bestimmten Kriterien, z. B. nach der Wellenlänge, dem Polarisationszustand oder (meist als Nebeneffekt) der Einfallsrichtung. Die bekannteren optischen Filter (Farbfilter, UV Filter) … Deutsch Wikipedia
Least mean squares filter — Least mean squares (LMS) algorithms are a class of adaptive filter used to mimic a desired filter by finding the filter coefficients that relate to producing the least mean squares of the error signal (difference between the desired and the… … Wikipedia
Stochastic gradient descent — is a general optimization algorithm, but is typically used to fit the parameters of a machine learning model.In standard (or batch ) gradient descent, the true gradient is used to update the parameters of the model. The true gradient is usually… … Wikipedia
Rank filter — is an image processing term. Typically, in digital filtering, pixels within a window are ranked by intensity values, and the center pixel is replaced with a new value. The new value is calculated as a function of the ranked pixels. Only the… … Wikipedia
Photographic filter — Four photographic filters. Clockwise, from top left, an infrared hot mirror filter, a polarising filter, and a UV filter. The larger filter is a polariser for Cokin style filter mounts. In photography and videography, a filter is a camera… … Wikipedia

Ensemble Kalman filter — The ensemble Kalman filter (EnKF) is a recursive filter suitable for problems with a large number of variables, such as discretizations of partial differential equations in geophysical models. The EnKF originated as a version of the Kalman filter … Wikipedia
Deblocking filter (video) — A deblocking filter is a video filter applied to blocks in decoded video to improve visual quality and prediction performance by smoothing the sharp edges which can form between macroblocks when block coding techniques are used. The filter aims… … Wikipedia
