Abstract

The invention provides a contour extraction method and device, a computer device and a computer readable storage medium. The contour extraction method comprises the steps that a background image of ashot scene is acquired, wherein the background image only contains the background without a target object; a first current image and a second current image of the shot scene are acquired, wherein thefirst current image is an image where the target object is included in the background, and the second current image is an image with depth information where the target object is included in the background; based on the depth information, the image content of the target object in the second current image is extracted; by means of the background image, the first current image is processed, and a first contour image of the target object is obtained; by means of the first contour image and the image content, calculation is carried out, and a second contour image of the target object is obtained. The contour extraction method and device help to improve the recognition precision of contour extraction.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a contour extraction method and device, a computer device and a readable storage medium. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are set forth in the claims and detailed description. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] In the existing special effects images, the extraction technology of the outline of the person is commonly used. However, in the current extraction technology of the outline of the person in the natural background, there are generally problems such as low precision of the edge of the person and the complexity of the algorithm, which makes it unsuitable for commercial use. requirements, and the actual experience is not good. Contents of the invention [0004] In view of this, it is necessary to provide a...
