Fast Gaussian Blur

Fast Gaussian Blur is an efficient technique used in image processing to soften or smooth an image by reducing sharp details. It approximates a traditional Gaussian blur, which spreads pixel values to create a blurring effect, but does so more quickly through mathematical shortcuts. This process helps reduce noise, improve visual quality, or create artistic effects without requiring much computational power, making it suitable for real-time applications like photo editing, video processing, or graphics rendering. Essentially, it makes images look smoother and more polished while saving time and resources.
