Multi-view scene segmentation and propagation

A depth-based effect may be applied to a multi-view video stream to generate a modified multi-view video stream. User input may designate a boundary between a foreground region and a background region, at a different depth from the foreground region, of a reference image of the video stream. Based on the user input, a reference mask may be generated to indicate the foreground region and the background region. The reference mask may be used to generate one or more other masks that indicate the foreground and background regions for one or more different images, from different frames and/or different views from the reference image. The reference mask and other mask(s) may be used to apply the effect to the multi-view video stream to generate the modified multi-view video stream. 可以对多视图视频流应用基于深度的效果以生成修改后的多视图视频流。用户输入可以指定所述视频流的参考图像的前景区域和与所述前景区域不同深度处的背景区域之间的边界。基于所述用户输入，可以生成参考掩模以指示所述前景区域和所述背景区域。所述参考掩模可以用于生成个或多个其它掩模，所述个或多个其它掩模指示来自所述参考图像的不同帧和/或不同视图的个或多个不同图像的前景区域和背景区域。所述参考掩模和其它掩模可以用于将所述效果应用于所述多视图视频流以生成所述修改后的多视图视频流。
