Problems solved by technology

[0005] However, for the large-area background objects that often appear in images that require background blurring, the current edge-preserving smoothing filtering algorithm will result in a blurred corresponding image obtained by using the disparity map to blur the background. In the image, the edge of each small-sized object in the background object will be highlighted, and at the same time, the edge of each small-sized object is not smooth, which eventually causes the display effect of the background object to be unnatural and unsmooth, affecting User's Visual Experience

Abstract

The embodiment of the invention provides an image processing method and device, an image blurring method and device, electronic equipment and a storage medium. The image processing method comprises the steps of conducting stereo matching on a first image collected by a first camera and a second image collected by a second camera to obtain a disparity map; performing semantic edge detection on thefirst image to determine a semantic edge region and a non-semantic edge region in the first image; and performing edge-preserving smooth filtering processing on the disparity map based on the gradientof the pixel in the first image, the semantic edge region and the non-semantic edge region.

Description

technical field [0001] The present application relates to the field, in particular to an image processing and blurring method, device, electronic equipment and storage medium. Background technique [0002] Background blurring is an important means to optimize the display effect of images. Especially for large-area background objects such as lawns and stone roads, the smoothness of lawns and stone roads is particularly important. If they are not smooth enough, they will cause problems such as blurring, agglomeration, and unevenness, which will affect people's visual experience. [0003] Currently, mobile terminals are generally configured with dual cameras. When shooting with dual cameras, for example, when shooting in portrait mode with dual cameras, binocular stereo matching is performed on the images collected by the main camera and the images collected by the secondary camera to obtain a disparity map, and the corresponding images are processed according to the disparity...
