Abstract

The invention relates to a picture processing method and apparatus. The method comprises the steps of acquiring an input picture; extracting a facial image form the input picture; acquiring a corresponding expression recognition result based on a pre-created expression classification model and acquiring a corresponding text based on the expression recognition result; and displaying the picture, the expression recognition result and / or the corresponding text. According to the invention, facial expression in the picture can be recognized, decorative words can be automatically added, the flexibility and diversity of a picture processing function are improved, convenience is brought to users in viewing and processing a picture, and user needs are met.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and device. Background technique [0002] At present, more and more users use digital devices such as mobile phones and cameras to take pictures, and users have more and more needs for beautification of photos, including the need to add text to photos for decoration. When users take some photos containing portraits, whether they are happy or sad, when they are accompanied by some specific text, it can better reflect the user's mood at that time. [0003] At present, text matching based on character expressions is mainly done manually, which has low efficiency and cannot meet user needs. Contents of the invention [0004] Embodiments of the present invention provide a method and device for image processing, aiming to automatically add corresponding decorative characters according to different facial expressions in the image, so as to ...
