Gaussian blur: a magical filter effect

Gaussian fuzzy is obviously different from other fuzzy algorithms. It is a filter function in Adobe Photoshop series software developed by Adobe Image Software Company of the United States. In this paper, the principle and characteristics of Gaussian blur will be discussed in depth to help readers better understand this magical filter effect.

Gaussian curve-based regulation

Gaussian blur adjusts the color value of pixels according to gaussian curve, and uses the calculation method of weighted average to selectively blur the image. This makes Gaussian blur perfectly preserve the outline of the character and present a more natural effect.

Application of Digital Image Processing

Gaussian blur is a common algorithm in digital image processing. It can selectively blur the image and make it softer and more natural. In Adobe Photoshop, this magical filter effect can be achieved in just a few simple steps.

Preserve the characteristics of the figure outline

Gaussian blur can perfectly preserve human contour and present a more natural effect. This makes it widely used in portrait photography and artistic painting.

Application of algorithm in digital world

In the digital world, all colors are just the combination of numbers, and all kinds of fuzzy effects are just the application of algorithms. Gaussian blur is a calculation method based on Gaussian function and weighted average, which carries out statistical and fuzzy processing on pixel color values and brings us such amazing visual experience.
