Abstract: One embodiment provides a method for rendering a virtual mark on a video frame, including: receiving the video frame, captured by a camera, comprising a scene; obtaining a three-dimensional model of a mark in the scene; obtaining a foreground mask of the video frame; denoting a predetermined region corresponding to a mark mask, wherein the mark mask is an image projection of the mark on the video frame; updating the mark mask to exclude foreground regions, wherein the updating comprises: partitioning the predetermined region into a plurality of segments; and filtering out, from the mark mask, foreground pixels based on the plurality of segments and the foreground mask; and rendering, on the video frame, the virtual mark using the updated mark mask. Other aspects are described and claimed.

Abstract: A method, apparatus, and computer program product are described that utilizes spatial modeling to represent foreground objects of an event to allow virtual graphics to be integrated into a background of the event in the presence of dynamic objects. The present invention detects a presence of dynamic objects within a region of interest from a video depicting the event. The present invention produces a suppression key corresponding to the dynamic object when present in the video or a suppression key with a default value when and where no dynamic object is present in the video.
