    • A method for replacing an object in an image is disclosed. The method comprises obtaining a first image having a first object. The first image is two-dimensional while the first object has feature portions. The method also comprises generating first image reference points on the first object and extracting object properties of the first object from the first image. The method further comprises providing a three-dimensional model being representative of a second image object and at least one of manipulating and displacing the three-dimensional model based on object properties of the first object. The method yet further comprises capturing a synthesized image containing a synthesized object from the at least one of manipulated and displaced three-dimensional model, the synthesized object having second image reference points and registering the second image reference points to the first image reference points for subsequent replacement of the first object with the synthesized object.
    • 公开了一种用于替换图像中的对象的方法。 该方法包括获得具有第一对象的第一图像。 第一个图像是二维的,而第一个对象具有特征部分。 该方法还包括在第一对象上生成第一图像参考点并从第一图像提取第一对象的对象属性。 该方法还包括提供代表第二图像对象的三维模型和基于第一对象的对象属性来操纵和移位三维模型中的至少一个。 所述方法还包括从所述操作和置换的三维模型中的至少一个捕获包含合成对象的合成图像,所述合成对象具有第二图像参考点,并将所述第二图像参考点登记到所述第一图像参考点用于随后的 用合成对象替换第一个对象。

    • With the ubiquity of new information technology and media, face and facial expression recognition technologies have been receiving significant attention. For face recognition systems, detecting the locations in two-dimension (2D) images where faces are present is a first step to be performed. However, face detection from a 2D image is a challenging task because of variability in imaging conditions, image orientation, pose, presence/absence of facial artefacts facial expression and occlusion. Existing efforts to address the shortcomings of existing face recognition systems involve technologies for creation of three-dimensional (3D) models of a human subject's face based on a digital photograph of the human subject. However, such technologies are computationally intensive nature and susceptible to errors and hence might not be suitable for deployment. An embodiment of the invention describes a method for synthesizing a plurality of 2D face images of an image object based on a synthesized 3D head object of the image object.
    • 随着新型信息技术和媒体的普及,面部和面部表情识别技术受到重视。 对于面部识别系统,检测存在脸部的二维(2D)图像中的位置是要执行的第一步。 然而,由于成像条件,图像取向,姿势,面部人工制品面部表情和闭塞的存在/不存在的变化,2D图像的面部检测是一项具有挑战性的任务。 解决现有面部识别系统的缺点的现有努力涉及基于人类受试者的数字照片来创建人类受试者面部的三维(3D)模型的技术。 然而,这些技术是计算密集型的并且易于出现错误,因此可能不适合部署。 本发明的实施例描述了一种用于基于图像对象的合成3D头部对象来合成图像对象的多个2D面部图像的方法。
