A system for detecting and incorporating three-dimensional objects into a video stream reads an input video data stream. The user specifies areas of attention wherein said areas of attention or hotspots. Tracking movement of the hotspots generating a trajectory of said at least one object. Generating a cloud of points and tracking said points to detect configurations of points most similar to the initially defined hotspot. Obtaining a three dimensional topology defining a volume of interest in a three-dimensional space. Building virtual structures or pseudo objects that are placed within a spherical environment generated on the input video.
