Abstract
Video up-conversion takes significant place in various application areas. One of important application areas is standard-definition (SD) video processing to get high-definition (HD) content for television and broadcast. However, high-quality up-conversion is a challenging task. Most practical implementations use spatial domain processing such as video frame interpolation for video up-scale. Meanwhile, due to sampling limitation the high-frequency component of output HD video cannot be efficiently reconstructed by applying only the spatial domain processing and high-quality up-conversion usually requires temporal domain processing as well. The authors propose practical implementation of such up-conversion technique providing significantly better visual results in comparison to traditional methods of SD to HD up-conversion.
