Scale Space Implementation - Finite-impulse-response (FIR) Smoothers
... a pair of real zeros at Z < 0, and approaches the discrete Gaussian in the limit of small t ... t can be used as the infinitesimal generator for the discrete Gaussian kernels described above ... At finer scales, the combination makes an excellent approximation to the discrete Gaussian if the poles and zeros each do about half the smoothing ...
Gaussian Function - Discrete Gaussian
... One may ask for a discrete analog to the Gaussian this is necessary in discrete applications, particularly digital signal processing ... A simple answer is to sample the continuous Gaussian, yielding the sampled Gaussian kernel ... However, this discrete function does not have the discrete analogs of the properties of the continuous function, and can lead to undesired effects, as described in the ...

To match the transfer function curvature at zero frequency of the discrete Gaussian, which ensures an approximate semi-group property of additive t, two poles at can be ...

Famous quotes containing the word discrete:

    We have good reason to believe that memories of early childhood do not persist in consciousness because of the absence or fragmentary character of language covering this period. Words serve as fixatives for mental images. . . . Even at the end of the second year of life when word tags exist for a number of objects in the child’s life, these words are discrete and do not yet bind together the parts of an experience or organize them in a way that can produce a coherent memory.
