Video coding using dynamic texture synthesis

In video coding system, because of the delay between current picture and the reference pictures, the temporal prediction is not good for the video sequences with nonlinear motion and global illumination change between frames. Dynamic textures are sequences of frames of moving scenes that exhibit certain stationary properties in time, which have great significance in applications such as video production and virtual simulation. This paper presents a new algorithm for dynamic texture extrapolation using for H.264 encoding and decoding system. The synthesized frames are used by the encoder for virtual reference frames choice in inter prediction and decoder for whole frames loss error concealment. The simulation results show that the proposed virtual reference frames choice algorithm improves encoding efficiency compared with the H.264 standard, and the proposed whole frames loss error concealment algorithm achieves significant improvement over the motion vector extrapolation method.
