Last year, CCITT announced the recommendation for "Video Codec for Audiovisual Services at p x 64kbit/s", called CCITT Rec. H.261. It prescribes a transmission image which is called CIF. Standardized TV-telephone equipment must transform original TV images to CIF images. A conventional method to get CIF images uses scale reduction filters. However, this method requires amount of hardware. Another method is cutting original images with CIF rectangular outline. This method is difficult to detect and track a human head area. This paper proposes a new head area tracking method in order to get CIF images. A human area will be tracked robustly another moving object invades to original images. This paper describes a basic theory and first simulation results.
