Gaussian Blur - Sample Gaussian Matrix

Sample Gaussian Matrix

This is a sample matrix, produced by sampling the Gaussian filter kernel (with σ = 0.84089642) at the midpoints of each pixel and then normalizing. Note that the center element (at ) has the largest value, decreasing symmetrically as distance from the center increases.

Note that 0.22508352 (the central one) is 1177 times larger than 0.00019117 which is just outside 3σ.

Famous quotes containing the words sample and/or matrix:

    “All that a city will ever allow you is an angle on it—an oblique, indirect sample of what it contains, or what passes through it; a point of view.”
    —Peter Conrad (b. 1948)

    ““The matrix is God?”
    “In a manner of speaking, although it would be more accurate ... to say that the matrix has a God, since this being’s omniscience and omnipotence are assumed to be limited to the matrix.”
    “If it has limits, it isn’t omnipotent.”
    “Exactly.... Cyberspace exists, insofar as it can be said to exist, by virtue of human agency.””
    —William Gibson (b. 1948)
