Abstract

The invention discloses a method and system for acquiring a head image in a picture. The method includes the following steps that: an obtained face in an original picture is detected, so that face detection data in the original picture can be acquired; an interception region corresponding to the face detection data is obtained according to a preset interception ratio and the face detection data, and the interception region is displayed; and cutting and saving processing is performed on the interception region, a required head image is obtained and is uploaded to a page of an application website so as to be displayed. According to the method and system provided by the technical schemes of the invention, the required head image can be automatically obtained from the picture. Compared with an existing method, the method does not need to carry out a plurality of times of manual interception, and therefore, the head image with the preset interception ratio can be quickly required.

Description

technical field [0001] The present invention relates to the technical field of face detection, in particular to a method and system for acquiring head portraits in pictures. Background technique [0002] With the development of the Internet, especially the mobile Internet technology, more and more users make friends, chat and trade through online community platforms. On this virtualized online community platform, in order to distinguish users and show individuality, the function of displaying user avatars is set up. [0003] At present, more and more people need to upload avatars on different websites, and due to the limitation of website page space, the uploaded images will generally be scaled to a smaller ratio for display. Therefore, in order to make the uploaded photo meet the requirements, it is usually necessary to find a photo with only the head or manually crop the photo. In the process of manually cropping photos, it often takes a lot of time to select a suitable ...
