A tag is a keyword or label that categorizes your question with other, similar questions. Using the right tags makes it easier for others to find and answer your question.
a mathematical representation of relationship between input and output (signal) of a linear, time-invariant system.
a mathematical technique to convert data in one domain to another. The most common example is using the Fourier Transform to convert data from the time domain to t…
Algorithms for processing video signals i.e. sequence of images either for enhancements, conversions or analysis of objects within it.
a computer-vision task that consists of detecting and tracking objects with a camera.
a wave-like oscillation with an amplitude that starts out at zero, increases, and then decreases back to zero.
A memoryless non-linear system whose input-output relation, written for example as out(t) = f(in(t)), is fully characterized by a non-linear function f(x).
a mathematical function that is zero-valued outside of some chosen interval.
Zero padding consists of extending a signal (or spectrum) with zeros to extend its time (or frequency band) limits.
a linear time-invariant (LTI) model of the piecewise constant output of a digital-to-analog converter (DAC).
The Z-transform converts a discrete time-domain signal, which is a sequence of real or complex numbers, into a complex frequency-domain representation.
