A hybrid motion estimation algorithm for secondary sp-frame coding is proposed. This hybrid algorithm effectively combines two existing techniques: one provides high coding efficiency and the other is computationally less intensive. The combination is based on inter-frame correlation, which is measured using the bit-count of its corresponding primary sp-frame. Experimental results show that this is an effective measure of selecting an appropriate domain for motion estimation in secondary sp-frame coding.
