Filter bank — A filter bank is an array of band pass filters that separates the input signal into several components, each one carrying a single frequency subband of the original signal. It also is desirable to design the filter bank in such a way that… … Wikipedia
Bloom filter — The Bloom filter, conceived by Burton H. Bloom in 1970, is a space efficient probabilistic data structure that is used to test whether an element is a member of a set. False positives are possible, but false negatives are not. Elements can be… … Wikipedia
Anti-aliasing filter — An anti aliasing filter is a filter used before a signal sampler, to restrict the bandwidth of a signal to approximately satisfy the sampling theorem. Since the theorem states that unambiguous interpretation of the signal from its samples is… … Wikipedia
Quadrature mirror filter — In digital signal processing, a quadrature mirror filter is a filter most commonly used to implement a filter bank that splits an input signal into two bands. The resulting high pass and low pass signals are often decimated by a factor of 2,… … Wikipedia
Low-pass filter — A low pass filter is a filter that passes low frequency signals but attenuates (reduces the amplitude of) signals with frequencies higher than the cutoff frequency. The actual amount of attenuation for each frequency varies from filter to filter … Wikipedia
Kalman filter — Roles of the variables in the Kalman filter. (Larger image here) In statistics, the Kalman filter is a mathematical method named after Rudolf E. Kálmán. Its purpose is to use measurements observed over time, containing noise (random variations)… … 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
