Gaussian filter. Learn how to use Gaussian filtering to blur images and remove noise and detail. . May 26, 2025 · A Gaussian filter is a linear smoothing operator widely used in image processing and computer vision applications. See the definition, properties, and examples of the Gaussian function and its 2D approximation. Apr 28, 2025 · A Gaussian Filter is a low-pass filter used for reducing noise (high-frequency components) and for blurring regions of an image. A Gaussian filter is a filter whose impulse response is a Gaussian function or an approximation to it. See the parameters, return value, notes and examples of this function. This filter uses an odd-sized, symmetric kernel that is convolved with the image. This Gaussian filter is a function of space alone, that is, nearby pixels are considered while filtering. Learn about its properties, definition, synthesis, and applications in electronics and signal processing.
