Abstract: Described herein are apparatus, systems and methods for shadow assisted object recognition and tracking. The methods performed by the apparatus and system include identifying a blob within a video image, the video image having at least one object and at least one shadow of the at least one object, the at least one shadow of the at least one object cast by at least one light source. Identifying the blob includes identifying an object projection corresponding to the at least one object and a shadow projection corresponding to the at least one shadow. A location of an object portion of the at least one object is determined based on the shadow projection.

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.
