Paper Abstract

To project block vectors to the new temporal interpolated fields, the known DFD evaluation is unreliable and responsible for the loss of fine details in the sequences. Two improved measures are presented to reduce the degradations. The basic ideas are the detected reliable pixel vector in structured areas should be remained and the temporal vector consistency is checked together with DFD values for the unreliable pixel vector. Initial simulation results have shown that obvious improvements in the scenery of fast motions. No large additional hardware effort is needed.
