Abstract

The invention provides an image processing method and apparatus, an electronic device and a computer-readable medium, which relate to the technical field of image processing. The method includes acquiring a target image after sparse grid processing; The sparse mesh in the target image is deformed and the deformed mesh is obtained. The target control points are determined based on the deformed meshand the sparse mesh. The target control points include the original key points and the deformed key points. The original key points include the original feature key points in the target image and/orthe original mesh vertices in the sparse mesh located in the background region. A dense mesh is constructed in the target image, and the dense mesh is deformed by the target control point to obtain adeformed dense mesh, thereby obtaining a deformed image of the target image by deforming the dense mesh. The invention can quickly generate dense and fine deformed mesh, and can improve the renderingeffect and the rendering performance of the image through the dense and fine deformed mesh.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, device, electronic equipment and computer readable medium. Background technique [0002] With the rapid development of smart terminal devices, smart terminal devices have been widely used among people. Especially with the development of Meitu software, people generally use various Meitu software on smart terminal devices. For example, it is widely used in short video software or live broadcast software. Among the short video software and live broadcast software, the frequently used Meitu software has the function of beautification or face shaping. [0003] Face shaping is a commonly used face beautification algorithm, which is widely used in image post-processing software and mobile devices such as mobile phones. By moving the key points of the face to the appropriate position, the deformation mesh is calculated, and finally the def...
