Several approaches were proposed that do not require priors about the object. X2Face [40] uses a dense motion field in order to generate the output video via image warping. Similarly to us they employ a reference pose that is used to obtain a canonical representation of the object. In our...
《First Order Motion Model for Image Animation》翻译与解读 Abstract Image animation consists of generating a video sequence so that an object in a source image is animated according to the motion of a driving video. Our framework addresses this problem without using any annotation or prior informat...
We presented a novel approach for image animation based on keypoints and local affine transformations. Our novel mathematical formulation describes the motion field between two frames and is efficiently computed by deriving a first order Taylor expansion approximation. In this way, motion is described ...
driving video. The major weakness of Monkey-Net is that it poorly models object appearance transformations in the keypoint neighborhoods assuming a zeroth order model (as we show in Sec. 3.1). This leads to poor generation quality in the case of large object pose changes (see Fig. 4). To...
可以看出,first-order 的效果还是很不错的,且该方法基于运动模型推导而出,在形式上也具有良好的可解释性。 基本框架 first-order 的算法框架如下图所示,主要包括三个部分的网络,keyporint detector 检测图像中的关键点,以及每个关键点对应的jaccobian矩阵;dense motion network 基于前面的结果生成最终的transform map...

首先，first-order motion model的算法框架包括三个主要部分：关键点检测器、每个关键点对应的雅可比矩阵以及密集运动网络。关键点检测器用于检测图像中的关键点，雅可比矩阵则记录了关键点的坐标变换，而密集运动网络则基于前两个结果生成最终的变换映射和遮罩映射。在经过变换映射和遮罩处理后，通过解码器生成...
