Abstract
AR elements are occluded in video image frames. A depth map is determined for an image frame of a video received from a video capture device. An AR graphical element for overlaying over the image frame is received. An element distance for AR graphical elements relative to a position of a user of the video capture device (e.g., the geographic position of the video capture device) is also received. Based on the depth map for the image frame, a pixel distance is determined for each pixel in the image frame. The pixel distances of the pixels in the image frame are compared to the element distance, and in response to a pixel distance for a given pixel being less than the element distance, the pixel of the image frame is displayed rather than a corresponding pixel of the AR graphical element.
