In image processing, a Gaussian blur (also known as Gaussian smoothing) is the result of blurring an image by a Gaussian function (named after mathematician and scientist Carl Friedrich Gauss). It is a widely used effect in graphics software, typically to reduce image noise and reduce detail. The visual effect of this … See more Mathematically, applying a Gaussian blur to an image is the same as convolving the image with a Gaussian function. This is also known as a two-dimensional Weierstrass transform. By contrast, convolving by a … See more Gaussian blur is a low-pass filter, attenuating high frequency signals. Its amplitude Bode plot (the log scale in the frequency domain) is a parabola. See more This sample matrix is produced by sampling the Gaussian filter kernel (with σ = 0.84089642) at the midpoints of each pixel and then … See more For processing pre-recorded temporal signals or video, the Gaussian kernel can also be used for smoothing over the temporal domain, since the data are pre-recorded and available in all directions. When processing temporal signals or video in real-time … See more How much does a Gaussian filter with standard deviation $${\displaystyle \sigma _{f}}$$ smooth the picture? In other words, how much does it reduce the standard deviation of pixel values in the picture? Assume the grayscale pixel values have a standard deviation See more A Gaussian blur effect is typically generated by convolving an image with an FIR kernel of Gaussian values. In practice, it is best to take advantage of the Gaussian blur’s separable property by dividing the process into two passes. In the first pass, a one … See more Edge detection Gaussian smoothing is commonly used with edge detection. Most edge-detection algorithms are sensitive to noise; the 2-D Laplacian filter, built from a discretization of the Laplace operator, is highly sensitive to noisy environments.
