| Summary: | The pose determination is very important especially for system such as face tracking, face recognition, face analysis and even face modeling system. Pose determination is a pre-requisite step for establishing face orientation of which will be used in determining the shape and structure of the face. Existing rotation-based pose determination that describes head movement using a single pivot point cannot describe rotation that involves changes in pivot point. In addressing the issue, this paper suggests a pose determination technique via usage of two pivot points. The paper will propose a definition for dual-pivot pose determination, suggest approaches to calculate head movement along these pivots, show a brief application for the dual-pivot and give comment on advantages and disadvantages of dual- pivot points.
