Embodiment Construction

[0030] The solutions of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0031] see figure 1 , figure 1 It is a schematic flowchart of an embodiment of the image blurring method of the present application. Specifically, the method of this embodiment includes the following steps:

[0032] Step S110: Determine the weights and pixel values ​​of the pixels contained in the image to be blurred, wherein the weights of the foreground pixels in the image to be blurred are lower than the weights of the background pixels.

[0033] The image to be blurred can be acquired by any image acquisition device, for example, it can be an ordinary camera, such as but not limited to a mobile phone camera, or a SLR camera, which is not limited herein. It is worth noting that when performing spot blurring on an image, the blurring strength is much greater than that of ordinary blurring, so it is easier to produce halo pro...

Abstract

The invention discloses an image blurring method, an image blurring device, equipment and a storage device. The image blurring method comprises the steps: determining weights and pixel values of pixelpoints contained in a to-be-blurred image, wherein the weights of foreground pixel points in the to-be-blurred image are lower than the weights of background pixel points; performing blurring processing on the background pixel points by utilizing the weights and the pixel values to obtain a blurred background image; and obtaining a blurred image according to the blurred background image and the foreground pixel points. According to the scheme, the 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 ...
