Image deformation method and device

The invention provides an image deformation method and device. The method comprises the steps of obtaining images or videos, identifying at least one target part of a to-be-deformed portrait in the image or the video; using a preset deformation algorithm to carry out deformation processing on a target part, wherein the deformation processing comprises one or more of the following processing: enlargement, reduction or displacement, so that portraits in an image and a video can be beautified automatically, a user does not need to beautify the image manually, the beautification mode is more intelligent and simpler, and the user experience is improved. The method provided by the invention can carry out deformation processing on the image and the video online in real time, and also can carry out deformation processing on the stored image and video offline, so that the application of the image deformation method is wider. 本发明提供一种图像变形方法和装置，包括：获取图像或视频，识别图像或者视频中待变形的人像的至少一个目标部位，使用预设的变形算法对目标部位进行变形处理，该变形处理包括以下处理中的一种或者多种：
