    • Generally, this disclosure provides methods and systems for real-time video communication with three dimensional perception image rendering through generated parallax effects based on identification, segmentation and tracking of foreground and background layers of an image. The system may include an image segmentation module configured to segment a current local video frame into a local foreground layer and a local background layer and to generate a local foreground mask based on an estimated boundary between the local foreground layer and the local background layer, wherein the current local video frame comprises a local color video image frame and a local image depth data frame; a face tracking module configured to track a position of a local user's face based on the current local video frame and one or more previous local video frames; a background layer estimation module configured to estimate a remote background layer associated with a current remote video frame and a remote foreground mask received from a remote video processor; and an image rendering module configured to render a 3D perception image based on the estimated remote background layer, the current remote video frame and the remote foreground mask received from the remote video processor, and the tracked position of the local user's face.
    • 通常,本公开提供了通过基于图像的前景和背景层的识别,分割和跟踪的生成的视差效应来实现具有三维感知图像呈现的实时视频通信的方法和系统。 该系统可以包括图像分割模块,该图像分割模块被配置为基于局部前景层和本地背景层之间的估计边界将当前局部视频帧分割成局部前景层和本地背景层并且生成局部前景屏蔽,其中 当前的本地视频帧包括局部彩色视频图像帧和局部图像深度数据帧; 面部跟踪模块,被配置为基于当前本地视频帧和一个或多个先前本地视频帧来跟踪本地用户的脸部的位置; 背景层估计模块,被配置为估计与当前远程视频帧相关联的远程背景层和从远程视频处理器接收的远程前景屏蔽; 以及图像渲染模块,被配置为基于从远程视频处理器接收的估计的远程背景层,当前远程视频帧和远程前景屏蔽以及本地用户的脸部的跟踪位置来渲染3D感知图像。
