Gaussian Filter

A Gaussian filter is a technique used in image processing to smooth and reduce noise or detail in an image. It works by averaging pixel values with their neighbors, giving more importance to closer pixels, based on a bell-shaped curve called a Gaussian. This results in a gentle blurring effect that maintains overall shapes while softening sharp edges and minimizing unwanted noise. The filter helps improve image quality for better analysis or visual clarity, widely used in photography, computer vision, and other digital imaging applications.
