51Minimum resolvable temperature difference — (MRTD) is a measure for assessing the performance of infrared cameras, and is inversely proportional to the modulation transfer function. Typically, an operator is asked to assess the minimum temperature difference at which a 4 bar target can be… …

53Adaptive filter — An adaptive filter is a filter that self adjusts its transfer function according to an optimizing algorithm. Because of the complexity of the optimizing algorithms, most adaptive filters are digital filters that perform digital signal processing… …
54TM-Sidhi program — The TM Sidhi program is a form of meditation introduced by Maharishi Mahesh Yogi in 1975. It is based on, and described as a natural extension of the Transcendental Meditation technique (TM).[1][2] The purpose of the TM Sidhi program is to… …
55Deconvolution — In mathematics, deconvolution is an algorithm based process used to reverse the effects of convolution on recorded data.[1] The concept of deconvolution is widely used in the techniques of signal processing and image processing. Because these… …
56Finite impulse response — A finite impulse response (FIR) filter is a type of a digital filter. The impulse response, the filter s response to a Kronecker delta input, is finite because it settles to zero in a finite number of sample intervals. This is in contrast to… …
57Signal to noise ratio (image processing) — The Signal to Noise Ratio (SNR) is used in image processing as a physical measure of the sensitivity of an imaging system. Industry standards measure SNR in decibels (dB) and therefore apply the 20 log rule to the pure SNR ratio. In turn,… …
58Wind power forecasting — A wind power forecast corresponds to an estimate of the expected production of one or more wind turbines (referred to as a wind farm) in the near future. By production is often meant available power for wind farm considered (with units kW or MW… …
59Comparison of analog and digital recording — This article compares the two ways in which sound is recorded and stored. Actual sound waves consist of continuous variations in air pressure. Representations of these signals can be recorded using either digital or analog techniques. An analog… …
60High dynamic range imaging — In image processing, computer graphics, and photography, high dynamic range imaging (HDRI) is a set of techniques that allows a greater dynamic range of exposures (the range of values between light and dark areas) than normal digital imaging… …
