Image processing method, device, device and computer-readable storage medium

Abstract

The present invention provides an image processing method, device, device, and computer-readable storage medium. The method includes: acquiring an image cropping instruction sent by a terminal device, wherein the image clipping instruction includes a human face image to be cropped; Corresponding at least one key point and the face image determine the target transformation affine matrix; perform a cropping operation on the face image according to the target transformation affine matrix to obtain a cropped target image; send the target image to the terminal device, so that The user performs editing processing on the target image. Since the average face is generated based on a large number of face images, it can represent the facial features of most people, and accordingly the target transformation affine matrix determined by the average face is used to crop the face image, which can effectively improve the efficiency of face cropping. Accuracy, and then the effect of special effect processing based on the cropped target image is better, which can better meet the needs of user image processing and improve user experience.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image processing method, device, equipment and computer-readable storage medium. Background technique [0002] With the development of science and technology, more and more application software has entered the life of users, gradually enriching the leisure life of users, such as short video APP and so on. Users can use videos, photos, etc. to record their lives, and upload short videos on the APP. [0003] In order to improve user experience, existing short video apps generally perform special effects processing on videos uploaded by users, such as adding stickers on users' faces. Before performing special effects processing on the face, it is first necessary to obtain an accurate face area, and the existing face area cropping methods often have low cropping accuracy, resulting in the loss of the content of the target area, or retaining too much non-target area content...
