Image synthesis method and device, and storage medium

Abstract

The embodiment of the invention provides an image synthesis method and device, and a storage medium. The method comprises the steps: carrying out the convex hull extraction of a target object image ina to-be-processed image, and obtaining a first boundary frame line; performing center reduction on the first boundary frame line to obtain a second boundary frame line; determining a target ray whereat least one connection point is located when the first preset material and the target object image are synthesized according to the target object image; determining at least one connection point ofthe first preset material and the target object image according to the first boundary frame line, the second boundary frame line, the target object image contour and the at least one target ray; and synthesizing the first preset material and the target object image according to the connection point and displaying a synthesis result. The allowable range of the connection point is defined based on the obtained first boundary frame line, second boundary frame line and target object image contour, and the position of the connection point determined in the range is reasonable, so that the positionof the first preset material in the synthesis result is reasonable, and the image synthesis effect expected by the user can be achieved.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of image processing, and in particular, to an image synthesis method, device, and storage medium. Background technique [0002] In the field of image processing technology, images are usually synthesized with preset materials, and preset materials are added to the image, for example, after a target object in the image is recognized, body and / or expression materials are added to the target object , can also control body and / or facial expressions, and can be applied to augmented reality (Augmented Reality, AR) technology, or image special effect editing and display, to increase the interest of image display and meet the diverse needs of users. [0003] In the prior art, when synthesizing the preset material with the target object, the synthesizing result is often unreasonable, and the image synthesizing effect expected by the user cannot be achieved, thereby affecting the image display e...
