Claim 7:
8. The method of claim 1:
wherein detecting the first set of objects within the first region-of-interest in the frame for each frame in the first sequence of frames comprises, for each frame in the first sequence of frames:
detecting the first set of objects within the first region-of-interest comprising a conference room in the frame; and

wherein detecting the object type, in the set of object types, of the object for each object in the first set of objects comprises, for a first object in the set of objects:
detecting a cluster of pixels representing a conference table in the frame; and
identifying the cluster of pixels as a table object type, in the set of object types;

wherein detecting the location of the object, at the time of the frame, within the region-of-interest in the frame for each object in the first set of objects comprises, for the first object:
calculating a centroid of the conference table based on the cluster of pixels; and
detecting the location of the centroid of the conference table, at the time of the frame, within the first region-of-interest in the frame;

wherein tracking the frequency of presence of the first object type, in the set of object types, intersecting the pixel over the first time period for each pixel in the set of pixels in the visualization layer comprises, for each pixel in the set of pixels:
calculating the frequency of presence of the table object type, in the set of object types, intersecting the pixel over the first time period based on the set of containers; and

wherein generating the heatmap of the first region-of-interest for the first time period comprises generating the heatmap representing locations of the table object type, in the set of object types, within the conference room for the first time period.
