Temporal-scalable coding based on image content

An object-based temporal scalability codec is proposed by introducing shape coding, a new motion estimation/compensation method, weighting techniques, and background composition. The major feature of this technique is determining the frame rate of the selected objects in the motion picture individually so that the motion of the selected region is smoother than that of the other area. The observation of the computer simulation proves that the proposed method achieves the better image quality and it enables us to represents the motion of the selected objects hierarchically
