Abstract
A video conference call system is provided with a camera to generate an input frame image of a conference room, where the video conference call system detects a human head for each meeting participant captured in the input frame image by applying a machine learning human head detector model to said input image frame, generates a head bounding box which surrounds each detected human head and identifies a corresponding meeting participant, extracts a pixel width measure and pixel height measure from each head bounding box, and applies the extracted pixel width measure and pixel height measure to one or more reverse lookup tables to extract meeting room coordinates for each meeting participant identified by a corresponding head bounding box.
