A method, apparatus and system identify the location of eyes. Specifically, a 360-degree camera is used to generate images of a face and identify the location of eyes in the face. A first light source on the axis of the 360-degree camera projects light towards the face and a first polar coordinate image is generated from the light that is returned from the face. A second light source off the axis of the 360-degree camera projects light towards the face and a second polar coordinate image is generated from the light that is returned from the face. The first and the second images are then compared to each other and a contrast area is identified to indicate the location of the eyes. The first and second polar coordinate images may be automatically converted into perspective images for various applications such as teleconferencing.
