Abstract
Traditionally, de-interlacing is implemented at the terminal-side as a post processing step, however this paper proposes a novel and advanced source-side de-interlacing method for high quality video content. It is an adaptive integration of texture-based intra-interpolation and inter-field motion compensation. Firsty, intra-interpolation based on texture similarity is proposed for wider search scope and better reconstruction performance. Motion compensation is strictly limited by vertical motion conditions and uniform motion check. Then, adaptive intra or inter mode decision is presented to further remove the compensated artifacts. Experiments show that the proposed technique can produce more convincing de-interlaced videos with less artifacts on both subjective and objective evaluation in comparison with other methods, including the leading multimedia tool ffmpeg. The parallelism nature of the proposed technique also makes it suitable for acceleration implementation on GPUs and thus is applicable for real time systems.
