Motion adaptive interpolation with horizontal motion detection for deinterlacing

A motion adaptive deinterlacing algorithm is presented in this paper. it consists of the ELA-Median directional interpolation, same-parity 4-field horizontal motion detection, morphological operation for noise reduction and adaptive threshold adjusting. The edges can be sharper when the ELA-Median directional interpolation is adopted. The same-parity 4-field horizontal motion detection detects faster motion and makes more accurate determinations about where objects are going to move. The morphological operation for noise reduction and adaptive threshold adjusting preserve the actual texture of the original objects. The proposed method achieves cost-efficient hardware implementation with low complexity, low memory usage, and high-speed processing capability. In addition, it consumes less time in producing high-quality images and allows the audience to enjoy a high-quality TV sequence on, their progressive devices. The experimental results show that the proposed algorithm is more cost-effective than previous systems.
