Abstract

The invention discloses an image blurring method, an image blurring device, equipment and a storage device. The image blurring method comprises the steps: acquiring an original background image of a to-be-blurred image, wherein the original background image comprises an invalid area corresponding to a foreground part of the to-be-blurred image; performing pixel value filling on the invalid area byutilizing an effective pixel value, located outside the invalid region, of the original background image to obtain a filling background image; performing blurring processing on the filling backgroundimage to obtain a blurred background image; and fusing the blurred background image and the foreground part of the to-be-blurred image to obtain a blurred image. According to the scheme, image blurring can be realized, and the halo problem is eliminated.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an image blurring method, an image blurring device, equipment, and a storage device. Background technique [0002] With the development of science and technology, people have higher and higher requirements for images. For example, for some images such as portrait photos or close-up photos, people hope that the image can achieve a blur effect. However, ordinary cameras, such as mobile phone cameras, cannot obtain blur effects in images captured by them, and image blur processing is often completed through post-processing technology. [0003] However, the effect of image blurring processing is not ideal at present, and the problem of halo is common. The halo problem can also be called "color leakage". Specifically, the foreground color at the image boundary leaks into the background, resulting in a blurred transition effect at the boundary. Therefore, the ...
