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.
for reducing the amount of data required to store a signal, whether lossy or lossless.
the field of study that aims to solve an underdetermined linear system of equations by exploiting the structure of the unknown data
Computer vision includes methods of processing, analyzing, images and high-dimensional data to form high level understanding and recognition of the scene or images.
A continuous signal or a continuous-time signal is a varying quantity (a signal) whose domain, which is often time, is a continuum.
a mathematical operation on two functions f and g, producing a third function that is typically viewed as a modified version of one of the original functions.
a measure of similarity of two waveforms as a function of a time-lag applied to one of them.
The Discrete Cosine Transform expresses a sequence of finitely many data points in terms of a sum of cosine functions oscillating at different frequencies.
a technique for reducing the number of samples in a discrete-time signal.
The concept of signal decomposition relates to the need to separate one component from the others in a signal; this can be achieved through a filtering operation which require a filter design stage.
in mathematics, the inverse operation of convolution signals. In general, the purpose of deconvolution is to find solutions of the convolution equation defined as: f * g = x. Where h is the recorde…
the act of extracting the original information-bearing signal from a modulated carrier wave.
a collection of techniques to remove unwanted noise from a signal. Typically this is done by filtering, but a variety of other techniques is available. Often combinations are used in sequ…
